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 GeneticsJul 09, 2021The c.260G>A (p.R87Q) alteration is located in exon 2 (coding exon 2) of the KBTBD4 gene. This alteration results from a G to A substitution at nucleotide position 260, causing the arginine (R) at amino acid position 87 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
