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 GeneticsMay 27, 2022The c.101G>A (p.R34Q) alteration is located in exon 3 (coding exon 2) of the MTFR1 gene. This alteration results from a G to A substitution at nucleotide position 101, causing the arginine (R) at amino acid position 34 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
