Genes affected

STRA6 (HGNC:30650): (signaling receptor and transporter of retinol STRA6) The protein encoded by this gene is a membrane protein involved in the metabolism of retinol. The encoded protein acts as a receptor for retinol/retinol binding protein complexes. This protein removes the retinol from the complex and transports it across the cell membrane. Defects in this gene are a cause of syndromic microphthalmia type 9 (MCOPS9). Several transcript variants encoding a few different isoforms have been found for this gene.

STRA6 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 7 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 15-74202216-AGT-GG is Pathogenic according to our data. Variant chr15-74202216-AGT-GG is described in ClinVar as [Pathogenic]. Clinvar id is 1139.Status of the report is no_assertion_criteria_provided, 0 stars.
