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 Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), QRICH1. . Gene score misZ 3.7104 (greater than the threshold 3.09). Trascript score misZ 3.7807 (greater than threshold 3.09). GenCC has associacion of gene with syndromic intellectual disability, schizophrenia, Ververi-Brady syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.892
