Genes affected

IRF2BPL (HGNC:14282): (interferon regulatory factor 2 binding protein like) This gene encodes a transcription factor that may play a role in regulating female reproductive function. [provided by RefSeq, Jun 2012]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 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. There are 16 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
