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.

RAD21 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• 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.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.921
• PP5: Variant 8-116854279-G-C is Pathogenic according to our data. Variant chr8-116854279-G-C is described in ClinVar as [Pathogenic]. Clinvar id is 35459.Status of the report is no_assertion_criteria_provided, 0 stars.
