Genes affected

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]

PTPMT1 links:

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]

The c.407G>A (p.R136H) alteration is located in exon 3 (coding exon 3) of the PTPMT1 gene. This alteration results from a G to A substitution at nucleotide position 407, causing the arginine (R) at amino acid position 136 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
