Genes affected
OXA1L (HGNC:8526): (OXA1L mitochondrial inner membrane protein) This gene encodes an evolutionarily conserved protein that is localized to the inner mitochondrial membrane. The encoded protein is essential for the translocation of the N-terminal tail of subunit 2 of cytochrome c oxidase, and is involved in the assembly of the cytochrome c oxidase and ATPase complexes of the mitochondrial respiratory chain.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.425T>C (p.V142A) alteration is located in exon 3 (coding exon 3) of the OXA1L gene. This alteration results from a T to C substitution at nucleotide position 425, causing the valine (V) at amino acid position 142 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
