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]

Dec 27, 2023

The c.222G>C (p.E74D) alteration is located in exon 2 (coding exon 2) of the PTPMT1 gene. This alteration results from a G to C substitution at nucleotide position 222, causing the glutamic acid (E) at amino acid position 74 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
