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]

The c.169C>A (p.Q57K) alteration is located in exon 3 (coding exon 3) of the REC8 gene. This alteration results from a C to A substitution at nucleotide position 169, causing the glutamine (Q) at amino acid position 57 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
