Genes affected

RD3 (HGNC:19689): (RD3 regulator of GUCY2D) This gene encodes a retinal protein that is associated with promyelocytic leukemia-gene product (PML) bodies in the nucleus. Mutations in this gene cause Leber congenital amaurosis type 12, a disease that results in retinal degeneration. Alternative splicing results in multiple transcript variants.

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 is located in the 3'-most 50 bp of the penultimate exon, 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 1-211481280-C-A is Pathogenic according to our data. Variant chr1-211481280-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 189794.Status of the report is no_assertion_criteria_provided, 0 stars.
