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]

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]

ACMG classification

Verdict is Benign. Variant got -7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.56).
• BP7: Synonymous conserved (PhyloP=1.24 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 5 AD gene.
