Genes affected

REC8 (HGNC:16879): (REC8 meiotic recombination protein) This gene encodes a member of the kleisin family of SMC (structural maintenance of chromosome) protein partners. The protein localizes to the axial elements of chromosomes during meiosis in both oocytes and spermatocytes. In the mouse, the homologous protein is a key component of the meiotic cohesion complex, which regulates sister chromatid cohesion and recombination between homologous chromosomes. Multiple alternatively spliced variants, encoding the same protein, have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 14-24177753-CCA-C is Pathogenic according to our data. Variant chr14-24177753-CCA-C is described in ClinVar as [Pathogenic]. Clinvar id is 1328952.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr14-24177753-CCA-C is described in Lovd as [Likely_pathogenic].
