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.

Pathogenic, no assertion criteria provided	literature only	OMIM	Jul 16, 2024	- -
Likely pathogenic, criteria provided, single submitter	clinical testing	Victorian Clinical Genetics Services, Murdoch Childrens Research Institute	Jul 17, 2023	Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Likely pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with mitochondrial complex I deficiency, nuclear type 28 (MIM#618249) (PMIDs: 25901006, 32722639). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to histidine. (I) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD (v2) <0.01 for a recessive condition (6 heterozygotes, 0 homozygotes). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2) (5 heterozygotes, 0 homozygotes). (I) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0600 - Variant is located in the annotated GRIM-19 family domain (DECIPHER). (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0803 - This variant has limited previous evidence of pathogenicity in an unrelated individual. This variant has been observed as homozygous in two siblings with developmental delay, seizures, hypotonia and optic atrophy. The variant was confirmed to be hetrozygous in their unaffected parents and an unaffected sibling (PMID: 25901006). (SP) 1001 - This variant has strong functional evidence supporting abnormal protein function. Western blot experiments in fibroblasts from patients homozygous for this variant showed reduced protein levels for NDUFA13 and other CI subunits. Blue native page experiments in these cells also showed a reduction in the abundance of CI and the CI, CIII, CIV supramolecular complex (PMID: 25901006). (SP) 1205 - This variant has been shown to be maternally inherited (by trio analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -
