Genes affected

PDE6C (HGNC:8787): (phosphodiesterase 6C) This gene encodes the alpha-prime subunit of cone phosphodiesterase, which is composed of a homodimer of two alpha-prime subunits and 3 smaller proteins of 11, 13, and 15 kDa. Mutations in this gene are associated with cone dystrophy type 4 (COD4). [provided by RefSeq, Mar 2010]

ACMG classification

Verdict is Pathogenic. Variant got 12 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 55 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-93612801-AG-A is Pathogenic according to our data. Variant chr10-93612801-AG-A is described in ClinVar as [Pathogenic]. Clinvar id is 487693.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr10-93612801-AG-A is described in Lovd as [Likely_pathogenic].
