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.

Ambry Genetics

Feb 06, 2023

The c.641G>A (p.R214Q) alteration is located in exon 6 (coding exon 5) of the MTFR1 gene. This alteration results from a G to A substitution at nucleotide position 641, causing the arginine (R) at amino acid position 214 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
