Genes affected

MARCHF4 (HGNC:29269): (membrane associated ring-CH-type finger 4) MARCH4 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. MARCH4 reduces surface accumulation of several membrane glycoproteins by directing them to the endosomal compartment (Bartee et al., 2004 [PubMed 14722266]).[supplied by OMIM, Apr 2010]

Ambry Genetics

Dec 21, 2023

The c.131T>G (p.M44R) alteration is located in exon 1 (coding exon 1) of the MARCH4 gene. This alteration results from a T to G substitution at nucleotide position 131, causing the methionine (M) at amino acid position 44 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
