ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

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.
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0000263 (4/152160) while in subpopulation NFE AF= 0.0000441 (3/68036). AF 95% confidence interval is 0.0000117. There are 0 homozygotes in gnomad4. There are 3 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
BS2
High AC in GnomAdExome4 at 87 AD gene.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2023The c.2264C>T (p.T755M) alteration is located in exon 11 (coding exon 9) of the QRICH1 gene. This alteration results from a C to T substitution at nucleotide position 2264, causing the threonine (T) at amino acid position 755 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
