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 undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-93620647-GA-G is Pathogenic according to our data. Variant chr10-93620647-GA-G is described in ClinVar as [Pathogenic]. Clinvar id is 487694.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr10-93620647-GA-G is described in Lovd as [Likely_pathogenic].
