Genes affected

PVR (HGNC:9705): (PVR cell adhesion molecule) The protein encoded by this gene is a transmembrane glycoprotein belonging to the immunoglobulin superfamily. The external domain mediates cell attachment to the extracellular matrix molecule vitronectin, while its intracellular domain interacts with the dynein light chain Tctex-1/DYNLT1. The gene is specific to the primate lineage, and serves as a cellular receptor for poliovirus in the first step of poliovirus replication. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]

CEACAM16-AS1 (HGNC:55317): (CEACAM16, CEACAM19 and PVR antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.008191377).
• BP6: Variant 19-44650057-G-A is Benign according to our data. Variant chr19-44650057-G-A is described in ClinVar as [Benign]. Clinvar id is 3034003.Status of the report is no_assertion_criteria_provided, 0 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0012 (183/152308) while in subpopulation EAS AF= 0.0276 (143/5190). AF 95% confidence interval is 0.0239. There are 2 homozygotes in gnomad4. There are 109 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 2 AR gene
