Genes affected

MARCHF2 (HGNC:28038): (membrane associated ring-CH-type finger 2) MARCH2 is a member of the MARCH family of membrane-bound E3 ubiquitin ligases (EC 6.3.2.19). MARCH enzymes add ubiquitin (see MIM 191339) to target lysines in substrate proteins, thereby signaling their vesicular transport between membrane compartments. MARCH2 reduces surface accumulation of several glycoproteins and appears to regulate early endosome-to-trans-Golgi network (TGN) trafficking (Bartee et al., 2004 [PubMed 14722266]; Nakamura et al., 2005 [PubMed 15689499]).[supplied by OMIM, Mar 2010]

The c.485G>A (p.G162E) alteration is located in exon 5 (coding exon 3) of the MARCH2 gene. This alteration results from a G to A substitution at nucleotide position 485, causing the glycine (G) at amino acid position 162 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
