Genes affected
MFN1 (HGNC:18262): (mitofusin 1) The protein encoded by this gene is a mediator of mitochondrial fusion. This protein and mitofusin 2 are homologs of the Drosophila protein fuzzy onion (Fzo). They are mitochondrial membrane proteins that interact with each other to facilitate mitochondrial targeting. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2023The c.1237A>G (p.M413V) alteration is located in exon 12 (coding exon 11) of the MFN1 gene. This alteration results from a A to G substitution at nucleotide position 1237, causing the methionine (M) at amino acid position 413 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
