Genes affected

MMD2 (HGNC:30133): (monocyte to macrophage differentiation associated 2) This gene encodes a member of the PAQR (progestin and adipoQ receptor) family. Members of this family are evolutionarily conserved with significant sequence identity to bacterial hemolysin-like proteins and are defined by a set of seven transmembrane domains. The protein encoded by this gene localizes to the Golgi apparatus to modulate Ras signaling. Alternative splicing results in multiple transcript variants and protein isoforms.
