Genes affected

C11orf80 (HGNC:26197): (TOP6B like initiator of meiotic double strand breaks) Predicted to be involved in meiotic DNA double-strand break formation and reciprocal meiotic recombination. Predicted to be located in chromosome. Implicated in gestational trophoblastic neoplasm. [provided by Alliance of Genome Resources, Apr 2022]

RCE1 (HGNC:13721): (Ras converting CAAX endopeptidase 1) This gene encodes an integral membrane protein which is classified as a member of the metalloproteinase family. This enzyme is thought to function in the maintenance and processing of CAAX-type prenylated proteins. [provided by RefSeq, Jul 2008]
