Genes affected

BIVM (HGNC:16034): (basic, immunoglobulin-like variable motif containing) Located in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

BIVM-ERCC5 (HGNC:43690): (BIVM-ERCC5 readthrough) This locus represents naturally occurring read-through transcription between the neighboring BIVM (basic, immunoglobulin-like variable motif containing) and ERCC5 (excision repair cross-complementing rodent repair deficiency, complementation group 5) genes on chromosome 13. The read-through transcript encodes a fusion protein that shares sequence identity with the products of each individual gene. [provided by RefSeq, Feb 2011]

ENSG00000305730 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.59).
• BP6: Variant 13-102839742-G-A is Benign according to our data. Variant chr13-102839742-G-A is described in ClinVar as [Benign]. Clinvar id is 783043.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=1.29 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00659 (1003/152302) while in subpopulation SAS AF = 0.0205 (99/4826). AF 95% confidence interval is 0.0172. There are 3 homozygotes in GnomAd4. There are 496 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 3 AR gene
