Genes affected

DMC1 (HGNC:2927): (DNA meiotic recombinase 1) This gene encodes a member of the superfamily of recombinases (also called DNA strand-exchange proteins). Recombinases are important for repairing double-strand DNA breaks during mitosis and meiosis. This protein, which is evolutionarily conserved, is reported to be essential for meiotic homologous recombination and may thus play an important role in generating diversity of genetic information. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2013]

The c.707G>T (p.R236L) alteration is located in exon 11 (coding exon 10) of the DMC1 gene. This alteration results from a G to T substitution at nucleotide position 707, causing the arginine (R) at amino acid position 236 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
