Genes affected

MARCHF7 (HGNC:17393): (membrane associated ring-CH-type finger 7) MARCH7 is a member of the MARCH family of membrane-bound E3 ubiquitin ligases (EC 6.3.2.19). MARCH proteins add ubiquitin (see MIM 191339) to target lysines in substrate proteins, thereby signaling their vesicular transport between membrane compartments (Bartee et al., 2004 [PubMed 14722266]).[supplied by OMIM, Mar 2010]

Collection Method: clinical testing

The c.361C>T (p.H121Y) alteration is located in exon 4 (coding exon 3) of the MARCH7 gene. This alteration results from a C to T substitution at nucleotide position 361, causing the histidine (H) at amino acid position 121 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
