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]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BP6: Variant 11-46701386-C-T is Benign according to our data. Variant chr11-46701386-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 1995226.Status of the report is criteria_provided_single_submitter, 1 stars.
