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.

Jul 20, 2021

The c.201C>G (p.C67W) alteration is located in exon 1 (coding exon 1) of the OXA1L gene. This alteration results from a C to G substitution at nucleotide position 201, causing the cysteine (C) at amino acid position 67 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
