Genes affected

DIP2C (HGNC:29150): (disco interacting protein 2 homolog C) This gene encodes a member of the disco-interacting protein homolog 2 family. The protein shares strong similarity with a Drosophila protein which interacts with the transcription factor disco and is expressed in the nervous system. [provided by RefSeq, Oct 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.012 CDS is truncated, and there are 0 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
