Genes affected

MARCHF9 (HGNC:25139): (membrane associated ring-CH-type finger 9) MARCH9 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. MARCH9 induces internalization of several membrane glycoproteins and directs them to the endosomal compartment (Bartee et al., 2004 [PubMed 14722266]; Hoer et al., 2007 [PubMed 17174307]).[supplied by OMIM, Apr 2010]

The c.697G>A (p.V233I) alteration is located in exon 3 (coding exon 3) of the MARCH9 gene. This alteration results from a G to A substitution at nucleotide position 697, causing the valine (V) at amino acid position 233 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
