Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2 BP7

The ENST00000361381.2(MT-ND4):​c.1251C>T​(p.Gly417=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. Variant has been reported in ClinVar as Uncertain significance (no stars).

• Frequency: Mitomap GenBank: 𝑓 0.0 (AC: 2)
• Consequence: MT-ND4 ENST00000361381.2 synonymous
• Clinical Significance: Uncertain significance no assertion criteria provided U:2 No linked disesase in Mitomap
• Conservation: PhyloP100: -20.0

Genes affected

MT-ND4 (HGNC:7459): (mitochondrially encoded NADH dehydrogenase 4) 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; Parkinson's disease; macular degeneration; and schizophrenia. Biomarker of Alzheimer's disease. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very low frequency in mitomap database: 0.0
• BP7: Synonymous conserved (PhyloP=-20 with no splicing effect.
