Genes affected

MTFR1 (HGNC:29510): (mitochondrial fission regulator 1) This gene encodes a mitochondrial protein that is characterized by a poly-proline rich region. A chicken homolog of this protein promotes mitochondrial fission and the mouse homolog protects cells from oxidative stress. A related pseudogene of this gene is found on chromosome X.

The c.797A>G (p.D266G) alteration is located in exon 7 (coding exon 6) of the MTFR1 gene. This alteration results from a A to G substitution at nucleotide position 797, causing the aspartic acid (D) at amino acid position 266 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
