Genes affected

MARCHF3 (HGNC:28728): (membrane associated ring-CH-type finger 3) This gene encodes a member of the membrane-associated RING-CH (MARCH) family. The encoded protein is an E3 ubiquitin-protein ligase that may be involved in regulation of the endosomal transport pathway. [provided by RefSeq, Mar 2013]
