ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.08311948).

BS1

Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000109 (16/1461894) while in subpopulation MID AF= 0.00052 (3/5768). AF 95% confidence interval is 0.000141. There are 1 homozygotes in gnomad4_exome. There are 12 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. 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 287 of the ZBTB24 protein (p.Lys287Arg). This variant is present in population databases (no rsID available, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with ZBTB24-related conditions. ClinVar contains an entry for this variant (Variation ID: 539532). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
