feat(report): flag a gene hit twice across engines, e.g. a deletion plus a variant on the other copy - #281
The report counted "both copies of a gene hit" from small variants only. A deletion of one copy plus a pathogenic variant on the other was missed: an exon deletion in MUTYH plus one MUTYH variant read as a single heterozygous hit, and the secondary-findings card listed it as not reported. The same gap hid an HBA deletion plus an HBA point variant, one SMN1 copy plus an SMN1 variant, and the 1q21.1 deletion plus the RBM8A low-expression allele that causes TAR syndrome. A variant inside a called deletion also read as homozygous when only one copy is there.
Fix
bin/collect_summary.py joins the deletions other engines call with the ClinVar hits, gene by gene (gene_deletions, two_hits). The deletions come from AnnotSV class 4 and 5 deletions (step 05), step 35's interval table, its HBA1/HBA2 count and Parascopy's SMN1 count.
A recessive gene hit by a deletion and a variant gets one line under the carrier list:
biallelic when the reads show trans: the variant is called 1/1 inside the deletion, or both calls carry read-backed phase (| genotype, same PS) on different copies;
possibly biallelic when the phase is unknown;
no line when phase puts both on the same copy.
A 1/1 hit inside a deletion is shown as hemizygous, in the carrier list and in the secondary-findings card.
In the secondary-findings card, a called deletion counts as one of the two variants a recessive gene (MUTYH, BTD, ATP7B) needs, unless phase puts it on the variant's copy. The reported row says which deletion it was counted with.
assets/carrier_genes.tsv: RBM8A's severity cell lists the two TAR low-expression alleles, c.-21G>A (rs139428292, chr1:145927447 C>T) and c.67+32G>C (rs201779890, chr1:145927328 C>G), from Albers et al. 2012 (PMID 22366785). Positions and ClinVar status were checked on dbSNP and ClinVar on 2026-11-04: VCV 30464 and 30465, both Pathogenic/Likely pathogenic/Pathogenic, low penetrance, so step 06 keeps them. On its own, such an allele stays set aside.
The couple screen (step 39) now counts a hypomorph of the severity cell beside a full loss of function in the other partner's same gene as a shared gene (bin/couple_report.py screen_couple). Without this, adding the TAR alleles to the severity cell would have dropped the TAR risk of a couple where one partner carries the allele and the other the 1q21.1 deletion. Two hypomorphs, or one alone, stay set aside, as before.
AnnotSV's SV_start is the base before the deleted bases, so the deletion's span starts one base after it. A 1/1 call at SV_start stays homozygous, and a listed gene that ends at that base is not paired.
Read-backed cis is checked first: a variant phased on the deletion's copy is no second hit, even inside the deletion. HIGH-impact records keep their phase set. The SF two-hit note sits only on the variant that pairs with the deletion. A count of 0 alpha-globin genes pairs with nothing. An unreadable carrier list is a note on the SF card.
Today step 05's checked table keeps no genotype, so an AnnotSV deletion has no phase in a pipeline run and pairs as possibly biallelic unless the hit is homozygous inside it. The docs say so. Keeping GT there needs bin/annotsv_postfilter.py, a follow-up outside this PR.
The line under the carrier list names the deletion callers it read and the ones it could not read, so a missing step never reads as "no second hit".
docs/interpreting-results.md explains the lines. It replaces the sentence that said a deletion in trans was not counted yet.
Decisions:
No new catalog column. The rule comes from what the catalogs already say: AR inheritance in the carrier list, report_if biallelic or hemizygous in assets/acmg_sf.tsv, and hypomorph/pseudodeficiency in the severity cells. A yes/no column on 3,311 rows would have repeated the inheritance column. The comment headers of both tables say how a deletion counts.
The couple screen keeps its rule for a deletion and a variant in one partner (two findings, with a note that the chance is higher in trans). The only change there is the hypomorph pairing above. It applies to every hypomorph of the list (RBM8A, BTD p.Asp444His, the GALT Duarte variants), since a low-function allele with a null on the other copy is a milder or full form of the condition for each; the row says the allele is a hypomorph.
No new e2e case. The rule is plain Python over the summary tables, so the unit test runs it in the self-tests job. The existing report e2e cases run on this head.
How it was checked
tests/test_cross_engine_biallelic.py, 40 checks on synthetic folders: MUTYH deletion plus a het hit, phased trans, two phase sets, cis, TAR, 1/1 inside and outside the deletion and at the AnnotSV padding base, SMN1 one and two copies, HBA three and four genes, no deletion caller, both rendered reports with the SF two-hit detail, the edges above, and the couple screen (RBM8A allele in one partner plus an RBM8A deletion in the other is shared at 1 in 4; the allele in both or in one alone gives no row).
Red on main's code in CI: Guard run https://github.com/GeiserX/OwnGenome/actions/runs/41780561226, on the commit with the test alone (22c2a44). Its unit-tests job fails tests/test_cross_engine_biallelic.py: the MUTYH and phase checks fail, then the file stopped at the TAR check. The next commit makes every check report instead of stopping. The test of b28d546, run locally against main's bin/ and assets/, fails 24 of its 31 checks.
Each of the 6 checks that pass on main is a control (cis, TAR allele with no deletion, 1/1 outside the deletion, two SMN1 copies, four alpha genes). Each was mutated once in the new code and went red: cis read as possibly; four HBA genes counted; two SMN1 copies counted; a no-change interval row counted; every hit read as inside the deletion.
The hemizygous checks (item 5) never ran red in CI, because the red CI run stopped before them. Their red is local: against main's bin/ and assets/ all five fail (carrier list, two-hit line, SF tier, first deleted base, text report), each with the call still read as homozygous.
The checks added in b28d546 were run against the previous head's bin/ locally, and both went red: "1/1 at AnnotSV's SV_start (the padding base) stays hom" (the call read hemizygous) and "couple: RBM8A allele in A + RBM8A deletion in B is a shared gene" (the row read one_partner, none shared).
The 6 edge checks added in 32aa7e4 fail locally against b28d546's bin/ and assets/. The SF-detail checks and the couple count check pass there (they pin behaviour that already worked), so each was shown red locally by a mutation: dropping two_hit from sf_rows, and counting hypomorphs with len(f).
Green on this head: the CI checks of this PR.

Summary by CodeRabbit
New Features
Carrier lists now report qualifying deletion-plus-variant findings, including whether they are biallelic, possibly biallelic, or hemizygous when supported by available evidence.
Secondary findings and rendered reports include two-hit explanations and deletion-caller read status.
Couple screening includes hypomorph findings when the other partner has a full-loss-of-function finding in the same gene.
Documentation
Updated result guidance to explain how deletion and variant combinations are assessed and reported.
…red before the rule
Synthetic folders: a MUTYH exon deletion plus a heterozygous hit, the same
with read-backed phase in trans and in cis, the 1q21.1 deletion plus the
RBM8A low-expression allele, a 1/1 hit inside a deletion, SMN1 and HBA.
Bead: pgp-pfw6.16
… variant on the other copy
The carrier list joins the deletions of AnnotSV (class 4 and 5), step 35's
interval table, its HBA count and Parascopy's SMN1 count with the ClinVar
hits, gene by gene. Read-backed phase in trans, or a 1/1 hit inside the
deletion (shown as hemizygous), gives biallelic; unknown phase gives
possibly biallelic; cis gives no line. In the SF tier the deletion counts
as one of the two variants MUTYH, BTD or ATP7B need. RBM8A's two TAR
low-expression alleles join the carrier list's severity column.

Carrier and secondary-finding results now assess ClinVar variants alongside detected deletions, using genotype and phase data where available. Reports include two-hit details and deletion-source status. Couple screening now records hypomorph findings and filters them based on the other partner’s findings.
Changes: Deletion-aware two-hit assessment
Layer / File(s)
Summary
Deletion and phase inputs bin/collect_summary.py, tests/test_cross_engine_biallelic.py
AnnotSV rows retain genotype and phase set fields. New helpers collect gene-overlapping deletions from AnnotSV, step 35 intervals, HBA counts, and Parascopy SMN1 counts, then assess variant-deletion pairs.
Carrier and secondary-finding assessment bin/collect_summary.py, tests/test_cross_engine_biallelic.py
Carrier-list generation and ACMG secondary-finding calculation use two-hit results. Homozygous variants inside deletions are marked hemizygous, and results include deletion-source read status. Tests cover phase outcomes, gene examples, copy-number cases, and unavailable inputs.
Rendered results and guidance bin/render_report.py, docs/interpreting-results.md, tests/test_cross_engine_biallelic.py
Reports include two-hit details when present and hemizygosity labels where supplied. The guidance describes deletion-plus-variant findings and phase outcomes. Tests check text and HTML report output.

…gene; AnnotSV deletions start after SV_start
The RBM8A TAR alleles joined the severity column, which set them aside in
the couple screen too: a TAR allele in one partner and an RBM8A deletion in
the other no longer gave a child risk. A hypomorph now counts when the other
partner has a full loss of function in the same gene; two hypomorphs, or one
alone, stay set aside. AnnotSV's SV_start is the base before the deleted
bases, so a 1/1 call there is no longer relabelled hemizygous.

Assert the SF two-hit detail in both rendered reports.
The report checks at lines 230-233 assert only the carrier-list Biallelic: MUTYH line and the hemizygous genotype. The SF row's two-hit text comes from sf_rows (bin/render_report.py:1638) and is not asserted in either format. A change that drops two_hit from sf_rows leaves these checks passing. For this fixture, the SF row carries biallelic with DEL chr1:45335000-45337000: ....

Add a cmd_screen test for a hypomorph ClinVar hit.
The new checks call screen_couple directly. The ClinVar hits (in listed genes / all) cell that cmd_screen writes is asserted only with 0 / 0, in tests/test_couple_report.py and tests/e2e/couple-common-sv-1.sh. No inspected test asserts a nonzero count for a partner with a hypomorph ClinVar hit in a listed gene. A change to that count would not fail these tests.
The intended value is not settled. The hypomorph is excluded from the numerator, but it remains a hit in a listed gene. Pin the value the report should show once that is decided.

Review comments at @bin/collect_summary.py:
- Around line 1780-1783: Update the checked SV table flow in
annotsv_postfilter.py to retain the FORMAT and sample columns required by
sec_annotsv’s genotype and phase-set extraction. Ensure those values remain
available to pair_phase for AnnotSV deletions, preserving its existing cis/trans
classification.
- Around line 3662-3663: Update the two-hit annotation logic so the note is
keyed to both gene and variant and is attached only to the paired variant, not
every row for that gene. Add a test with one trans and one cis variant in the
same gene, confirming only the trans variant receives the note.
- Around line 3467-3469: Update the variant-classification flow so the cis-phase
check runs before the `inside` deletion branch. When a heterozygous variant and
deletion have the same PS and matching `1|0` phase, classify the variant as cis
with no second hit; for contradictory phased calls, avoid describing phase as
unknown.
- Around line 3631-3634: Update the `carrier_genes()` unreadable-asset handling
and secondary-findings card so a `carrier_genes.tsv` read failure is surfaced as
an explicit note rather than silently treated as no deletions. Do not present
missing interval-dependent results as negative; preserve or mark them
unavailable unless the required spans can be established.
- Around line 3430-3437: Update the count-based HBA deletion logic in
`gene_deletions` so a copy count of 0 does not add unphased HBA1/HBA2 deletions
that `pair_phase` can interpret as possibly biallelic. Keep the existing
per-gene deletion behavior for counts from 1 through 3.
- Around line 3395-3404: Update check_rows to retain the sample genotype in each
checked row, and have sec_annotsv pass it through to gene_deletions so rows with
GT 0/0 are excluded while missing genotypes remain included. Check and preserve
the intended phase behavior in pair_phase for the newly retained genotype data.
- Around line 3401-3402: Update the gene loop around `over` and `add` to check
each gene’s coordinates against the deleted interval from `first` through
`int(b)` before adding it as an inside hit. Exclude genes that overlap only the
VCF anchor base, while preserving inside hits for genes that intersect the
deleted bases.
- Around line 3618-3619: Retain the variant’s phase set in each
`csq_high_impact_genes` record and propagate it through `acmg_sf_tier` into the
record supplied to `two_hits` instead of setting `ps` to `None`. Ensure deletion
records also retain their phase set so `pair_phase` can distinguish cis from
trans.

… HIGH-impact phase
The SF two-hit note is now attached only to the variant that pairs with the
deletion, read-backed cis wins over the inside-deletion rule, HIGH-impact
records keep their phase set, a gene AnnotSV names that ends at the padding
base gets no pair, 0 alpha-globin genes pair with nothing, and an unreadable
carrier list is a note on the SF card.
Review of b28d546, the two nitpicks in the review body, both fixed in 32aa7e4:
tests/test_cross_engine_biallelic.py 229-233: the report fixture now has step 23's clinical VCF, so the SF card is drawn, and both reports are checked for the SF row's 'biallelic with DEL' detail. A mutation that drops two_hit from sf_rows turns both checks red.
tests/test_cross_engine_biallelic.py 243-248: decided the count: the assessed table shows a hypomorph as no finding of the listed genes, since it is set aside on its own (a hit of all, so '0 / 1'). A couple_report.py screen run now checks '| A | 0 / 1 |' and the gap line. Counting it with len(f) turns the check red.
…e or the row itself
## The problem
The genome viewer only ran on 127.0.0.1 of the machine that holds the data, with no login. From the live site on a phone or another laptop, the report's "see the reads" links pointed at a port that was not there. In the report itself, only three tables had viewer links, as one line of links under each table, so the Slivar pairs, the AnnotSV class 4-5 SVs, the deep intronic sites, the cDNA scan and the mosaic calls had no way to open the reads.
## The fix
- **Viewer on the live site.** A new plugin, `bin/owngenome_live_viewer.py`, serves the same igv.js page for every run at `/runs/<run>/viewer/`, behind the site's password. It uses the same page, Content-Security-Policy and default files as `scripts/owngenome-view.sh`: the run folder's BAM or CRAM, VCF and SV VCF, each with its index, plus `REF_FASTA`. A track whose file or index is a symlink out of `GENOME_DIR` is left out, with both files. A file name with a space, `#` or `?` is matched after unquoting the request path, as the standalone server does. The served report gets its viewer links pointed there. `scripts/owngenome-live.sh` passes the reference and igv.js, and downloads igv.js on the first start, checked by sha256. Without a reference index or igv.js the site starts without the viewer and says why. `OWNGENOME_LIVE_VIEWER=off` leaves the viewer out. Opening the viewer writes one access-log row. The byte ranges write none.
- **One pin.** `IGV_JS_VERSION` and `IGV_JS_SHA256` move from `scripts/owngenome-view.sh` to `versions.env`, so both launchers read the same pin. `docs/versions.md` lists only images, so it is unchanged (`gen-versions-doc.sh --check` passes).
- **A Viewer column on every findings table.** ClinVar hits, secondary findings, mitochondrial variants, deep intronic sites, the cDNA scan, AnnotSV class 4-5 and the calls moved to class 3, slivar's pairs in trans, mosaic alterations and Exomiser's ranked variants each end with a Viewer column. It holds one link per row, to the row's position, or a range for an SV, a region or a pair. A note under each table says how to start the viewer. This replaces the single line of links under three tables. Both report paths get it, since bash and Nextflow both render through `bin/render_report.py`.
- `assets/viewer/serve.py` gains `sample_files` and `send_file` (the byte-range sender, moved out of the handler), so the plugin reuses them instead of copying them.
Output change, as the 1.0 contract asks: the HTML report gains a column on these tables. No cell is renamed or removed, and the text and JSON outputs are unchanged.
Privacy, said plainly in `docs/live-site.md` and `docs/viewer.md`: from the live site the reads cross the network to the browser that logged in. Only the byte ranges igv.js asks for travel, and only after the login. Off loopback, use TLS. The standalone viewer keeps its "no login, do not expose the port" warning.
### Decisions taken in this PR
- **A trailing Viewer column, not a link inside the locus cell.** The bead says "in the locus cell". Wrapping the locus text in a link would break exact cell pins in five e2e cases owned by other lanes (`50-html-report-24.sh`, `annotsv-report-section-1-chain.sh`, `clinvar-combined-allele-1.sh`, `construct-scan-1-both.sh`, `report-followups-1-sections.sh`). One of them is a `lacks` check that would have gone silently true. A column of its own keeps every existing cell's text and keeps main true. Each row still gets its own link.
- **Renamed paths.** The plan names `bin/pgp_live_viewer.py` and `scripts/pgp-live.sh`. Since the rename these are `bin/owngenome_live_viewer.py` (the live server loads only `owngenome_live_*.py` plugins) and `scripts/owngenome-live.sh`. The test is `tests/test_live_viewer.py`, as planned.
- **The page's header line.** `assets/viewer/index.html` says "served from this computer only". The plugin swaps that line for "served by the run site, behind its login" when it serves the page, so the page stays true without editing the shared file.
- `tests/test_isec_columns.sh` needed no change: it pins the chromosome, gene and genotype cells, not the end of the row.
## How it was checked
CI on head f3189df. Every check except e2e is green. The Guard run's unit-tests job ran `tests/test_viewer.py`, `tests/test_live_viewer.py` and `tests/test_collect_summary.py` with both headless Chrome checks: https://github.com/GeiserX/OwnGenome/actions/runs/41854962919
Local runs on this branch (unit tests only, no containers):
- `python3 tests/test_viewer.py`: ALL PASS. That covers the pin read from `versions.env` with its sha256, no pin left in `owngenome-view.sh`, a Viewer cell in every findings table, and headless Chrome on the standalone page.
- `python3 tests/test_live_viewer.py`: ALL PASS. That covers the login redirect and 401s, the viewer policy, BAM byte ranges (206, 416), refused files and runs (404), report links rewritten to `/runs/S/viewer/`, one access-log row, a symlinked BAM left out, a site without the flags, and igv.js ready with 3 tracks in headless Chrome.
- `tests/test_collect_summary.py`, `tests/test_render_report.py`, `tests/test_owngenome_live.py`, `tests/test_live_post.sh` and the other report tests: ALL PASS.
Red controls:
- **Mismatched pin.** With `IGV_JS_SHA256` in `versions.env` changed to a wrong value, `tests/test_viewer.py` exits 1: `[FAIL] owngenome-view.sh: the server starts ... Download attempt 1/3 failed its check: sha256 checksum of igv.min.js is 87b991ae..., expected 000091ae...`.
- **Exomiser table.** With `bin/render_report.py` of the previous head (no Viewer column on the Exomiser table), the table check names exactly that table: `Exomiser ranking: the header does not end with the Viewer column`, `... a row whose last cell is not a viewer link to chr3:700`, `... no viewer note in the card under the table`.
- **Links removed.** Inside `tests/test_viewer.py`, every CI run renders the report with the Viewer cell emptied, and the table check must then name all 10 tables (`report: control: ...`).
- **Planted mistakes.** Inside `tests/test_live_viewer.py`, every CI run loads four planted copies of the plugin: one serves any file of the run folder, one drops the report filter, one compares the still-quoted file name, one serves an index symlinked out of `GENOME_DIR`. The checks must fail on each (`control: ...`).

Problem
The report counted "both copies of a gene hit" from small variants only. A deletion of one copy plus a pathogenic variant on the other was missed: an exon deletion in MUTYH plus one MUTYH variant read as a single heterozygous hit, and the secondary-findings card listed it as not reported. The same gap hid an HBA deletion plus an HBA point variant, one SMN1 copy plus an SMN1 variant, and the 1q21.1 deletion plus the RBM8A low-expression allele that causes TAR syndrome. A variant inside a called deletion also read as homozygous when only one copy is there.
Fix
bin/collect_summary.pyjoins the deletions other engines call with the ClinVar hits, gene by gene (gene_deletions,two_hits). The deletions come from AnnotSV class 4 and 5 deletions (step 05), step 35's interval table, its HBA1/HBA2 count and Parascopy's SMN1 count.biallelicwhen the reads show trans: the variant is called 1/1 inside the deletion, or both calls carry read-backed phase (|genotype, same PS) on different copies;possibly biallelicwhen the phase is unknown;assets/carrier_genes.tsv: RBM8A's severity cell lists the two TAR low-expression alleles, c.-21G>A (rs139428292, chr1:145927447 C>T) and c.67+32G>C (rs201779890, chr1:145927328 C>G), from Albers et al. 2012 (PMID 22366785). Positions and ClinVar status were checked on dbSNP and ClinVar on 2026-11-04: VCV 30464 and 30465, both Pathogenic/Likely pathogenic/Pathogenic, low penetrance, so step 06 keeps them. On its own, such an allele stays set aside.bin/couple_report.py screen_couple). Without this, adding the TAR alleles to the severity cell would have dropped the TAR risk of a couple where one partner carries the allele and the other the 1q21.1 deletion. Two hypomorphs, or one alone, stay set aside, as before.SV_startis the base before the deleted bases, so the deletion's span starts one base after it. A 1/1 call atSV_startstays homozygous, and a listed gene that ends at that base is not paired.bin/annotsv_postfilter.py, a follow-up outside this PR.docs/interpreting-results.mdexplains the lines. It replaces the sentence that said a deletion in trans was not counted yet.Decisions:
report_ifbiallelic or hemizygous inassets/acmg_sf.tsv, and hypomorph/pseudodeficiency in the severity cells. A yes/no column on 3,311 rows would have repeated the inheritance column. The comment headers of both tables say how a deletion counts.How it was checked
tests/test_cross_engine_biallelic.py, 40 checks on synthetic folders: MUTYH deletion plus a het hit, phased trans, two phase sets, cis, TAR, 1/1 inside and outside the deletion and at the AnnotSV padding base, SMN1 one and two copies, HBA three and four genes, no deletion caller, both rendered reports with the SF two-hit detail, the edges above, and the couple screen (RBM8A allele in one partner plus an RBM8A deletion in the other is shared at 1 in 4; the allele in both or in one alone gives no row).tests/test_cross_engine_biallelic.py: the MUTYH and phase checks fail, then the file stopped at the TAR check. The next commit makes every check report instead of stopping. The test of b28d546, run locally against main'sbin/andassets/, fails 24 of its 31 checks.bin/andassets/all five fail (carrier list, two-hit line, SF tier, first deleted base, text report), each with the call still read as homozygous.bin/locally, and both went red: "1/1 at AnnotSV's SV_start (the padding base) stays hom" (the call read hemizygous) and "couple: RBM8A allele in A + RBM8A deletion in B is a shared gene" (the row readone_partner,none shared).bin/andassets/. The SF-detail checks and the couple count check pass there (they pin behaviour that already worked), so each was shown red locally by a mutation: droppingtwo_hitfromsf_rows, and counting hypomorphs withlen(f).Bead: pgp-pfw6.16
