Genes affected

REC114 (HGNC:25065): (REC114 meiotic recombination protein) The protein encoded by this gene is orthologous to the mouse meiotic recombination protein REC114, which is involved in DNA double-strand break formation during meiosis. The encoded protein is conserved in most eukaryotes and was first discovered and characterized in yeast. [provided by RefSeq, Feb 2017]
