Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PP2

Missense variant where missense usually causes diseases, QRICH1

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

The 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. -
