Genes affected

CMTM2 (HGNC:19173): (CKLF like MARVEL transmembrane domain containing 2) This gene belongs to the chemokine-like factor gene superfamily, a novel family that links the chemokine and the transmembrane 4 superfamilies of signaling molecules. The protein encoded by this gene may play an important role in testicular development. [provided by RefSeq, Jul 2008]
