Genes affected

MARCHF5 (HGNC:26025): (membrane associated ring-CH-type finger 5) MARCH5 is a ubiquitin ligase of the mitochondrial outer membrane that plays a role in the control of mitochondrial morphology by regulating mitofusin-2 (MFN2; MIM 608507) and DRP1 (DNM1L; MIM 603850) (Nakamura et al., 2006 [PubMed 16936636]).[supplied by OMIM, Mar 2008]

The c.470A>G (p.K157R) alteration is located in exon 4 (coding exon 4) of the MARCH5 gene. This alteration results from a A to G substitution at nucleotide position 470, causing the lysine (K) at amino acid position 157 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
