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

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.11076614).
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000197 (3/152206) while in subpopulation AFR AF= 0.0000724 (3/41448). AF 95% confidence interval is 0.0000192. There are 0 homozygotes in gnomad4. There are 1 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2024The c.2323A>G (p.M775V) alteration is located in exon 11 (coding exon 9) of the QRICH1 gene. This alteration results from a A to G substitution at nucleotide position 2323, causing the methionine (M) at amino acid position 775 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
