…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.

Bead: pgp-pfw6.16
…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.
… 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.
