Genes affected
KBTBD4 (HGNC:23761): (kelch repeat and BTB domain containing 4)
PTPMT1 (HGNC:26965): (protein tyrosine phosphatase mitochondrial 1) Predicted to enable phosphatidylglycerophosphatase activity and phosphatidylinositol-4,5-bisphosphate 5-phosphatase activity. Involved in regulation of intrinsic apoptotic signaling pathway. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]
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 27, 2021The c.1372G>T (p.V458L) alteration is located in exon 4 (coding exon 4) of the KBTBD4 gene. This alteration results from a G to T substitution at nucleotide position 1372, causing the valine (V) at amino acid position 458 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
