Variant summary

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

The ENST00000361453.3(MT-ND2):​c.636T>C​(p.Thr212=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. Variant has been reported in ClinVar as Uncertain significance (★).

• Frequency: Mitomap GenBank: 𝑓 0.00020 (AC: 14)
• Consequence: MT-ND2 ENST00000361453.3 synonymous
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1 No linked disesase in Mitomap
• Conservation: PhyloP100: -10.8

Genes affected

MT-ND2 (HGNC:7456): (mitochondrially encoded NADH dehydrogenase 2) 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; multiple sclerosis; myocardial infarction; neurodegenerative disease (multiple); and urinary bladder cancer.
