Genes affected

NDUFA13 (HGNC:17194): (NADH:ubiquinone oxidoreductase subunit A13) This gene encodes a subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), which functions in the transfer of electrons from NADH to the respiratory chain. The protein is required for complex I assembly and electron transfer activity. The protein binds the signal transducers and activators of transcription 3 (STAT3) transcription factor, and can function as a tumor suppressor. The human protein purified from mitochondria migrates at approximately 16 kDa. Transcripts originating from an upstream promoter and capable of expressing a protein with a longer N-terminus have been found, but their biological validity has not been determined.

Invitae

Sep 27, 2022

This sequence change replaces threonine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 42 of the NDUFA13 protein (p.Thr42Asn). This variant is present in population databases (rs146785123, gnomAD 0.2%). This variant has not been reported in the literature in individuals affected with NDUFA13-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
