Genes affected

ZNF408 (HGNC:20041): (zinc finger protein 408) The protein encoded by this gene contains ten tandem zinc fingers and an N-terminal SET domain, so it is likely a DNA binding protein that interacts with other proteins. In adults, the encoded protein is expressed most highly in retina. Consequently, defects in this gene have been associated with familial exudative vitreoretinopathy (FEVR) and retinitis pigmentosa (RP). [provided by RefSeq, Dec 2016]

ZNF408 (HGNC:):

ACMG classification

Verdict is Pathogenic. Variant got 11 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 11-46702730-CGT-C is Pathogenic according to our data. Variant chr11-46702730-CGT-C is described in ClinVar as [Pathogenic]. Clinvar id is 204316.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr11-46702730-CGT-C is described in Lovd as [Likely_pathogenic].
