Genes affected

RAD21 (HGNC:9811): (RAD21 cohesin complex component) The protein encoded by this gene is highly similar to the gene product of Schizosaccharomyces pombe rad21, a gene involved in the repair of DNA double-strand breaks, as well as in chromatid cohesion during mitosis. This protein is a nuclear phospho-protein, which becomes hyperphosphorylated in cell cycle M phase. The highly regulated association of this protein with mitotic chromatin specifically at the centromere region suggests its role in sister chromatid cohesion in mitotic cells.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RAD21. . Gene score misZ 2.6421 (greater than the threshold 3.09). Trascript score misZ 3.6451 (greater than threshold 3.09). GenCC has associacion of gene with Cornelia de Lange syndrome, Cornelia de Lange syndrome 4, Mungan syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.11448234).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000197 (3/152066) while in subpopulation EAS AF= 0.000577 (3/5198). AF 95% confidence interval is 0.000157. There are 0 homozygotes in gnomad4. There are 0 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

This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 526 of the RAD21 protein (p.Glu526Gln). This variant is present in population databases (rs373026310, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with RAD21-related conditions. ClinVar contains an entry for this variant (Variation ID: 473192). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
