Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP7 BS2

The ENST00000361567.2(MT-ND5):​c.141T>C​(p.Ser47=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Mitomap GenBank: 𝑓 0.0050 (AC: 307)
• Consequence: MT-ND5 ENST00000361567.2 synonymous
• Clinical Significance: Not reported in ClinVar Possible-HCM-susceptibility
• Conservation: PhyloP100: 0.166

Genes affected

MT-ND5 (HGNC:7461): (mitochondrially encoded NADH dehydrogenase 5) Enables NADH dehydrogenase (ubiquinone) activity. Involved in mitochondrial electron transport, NADH to ubiquinone and mitochondrial respiratory chain complex I assembly. Part of mitochondrial respiratory chain complex I. Implicated in Leber hereditary optic neuropathy; Leigh disease; and MELAS syndrome. [provided by Alliance of Genome Resources, Apr 2022]
