ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.4133763).
BS1
Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.00000889 (13/1461688) while in subpopulation AFR AF = 0.000299 (10/33480). AF 95% confidence interval is 0.000161. There are 0 homozygotes in GnomAdExome4. There are 3 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 641 of the ZNF341 protein (p.Lys641Arg). This variant is present in population databases (rs766030942, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with ZNF341-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
