Genes affected

QRICH1 (HGNC:24713): (glutamine rich 1) Enables DNA binding activity. Involved in several processes, including PERK-mediated unfolded protein response; intrinsic apoptotic signaling pathway in response to endoplasmic reticulum stress; and positive regulation of transcription, DNA-templated. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000290315 (HGNC:):

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 0.0669 CDS is truncated, and there are 2 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
