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 GeneticsJan 16, 2024The c.298C>T (p.L100F) alteration is located in exon 2 (coding exon 2) of the OXA1L gene. This alteration results from a C to T substitution at nucleotide position 298, causing the leucine (L) at amino acid position 100 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
