Variant chr14-22766759-C-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_005015.5(OXA1L):c.58C>G(p.Arg20Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000041 in 1,461,814 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R20P) has been classified as Uncertain significance.

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.

The c.238C>G (p.R80G) 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 238, causing the arginine (R) at amino acid position 80 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
