Genes affected

GMCL2 (HGNC:19717): (germ cell-less 2, spermatogenesis associated) This locus shares a high degree of identity with the multi-exon germ cell-less gene on chromosome 2. Despite its single-exon nature, this chromosome 5 locus contains an open reading frame that could putatively encode a full-length germ cell-less related protein. [provided by RefSeq, Jul 2008]
