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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.65C>T (p.S22L) alteration is located in exon 2 (coding exon 1) of the MTFR1 gene. This alteration results from a C to T substitution at nucleotide position 65, causing the serine (S) at amino acid position 22 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
