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]

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. Fraction of 0.0219 CDS is truncated, and there are 0 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 3-49030501-CTT-C is Pathogenic according to our data. Variant chr3-49030501-CTT-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 2505228.Status of the report is criteria_provided_single_submitter, 1 stars.
