Genes affected
KBTBD4 (HGNC:23761): (kelch repeat and BTB domain containing 4)
NDUFS3 (HGNC:7710): (NADH:ubiquinone oxidoreductase core subunit S3) This gene encodes one of the iron-sulfur protein (IP) components of mitochondrial NADH:ubiquinone oxidoreductase (complex I). Mutations in this gene are associated with Leigh syndrome resulting from mitochondrial complex I deficiency.[provided by RefSeq, Apr 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.875A>G (p.Q292R) alteration is located in exon 4 (coding exon 4) of the KBTBD4 gene. This alteration results from a A to G substitution at nucleotide position 875, causing the glutamine (Q) at amino acid position 292 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
