Functional studies support a deleterious effect on mitochondrial morphology and cellular reactive oxygen species level (Zhang et al., 2016; Olichon et al., 2007); Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; This variant is associated with the following publications: (PMID: 33300680, 27858935, 30293569, 22779427, 21745197, 23916084, 25564500, 11017080, 17167772, 26867657, 32025183)

This variant has not been reported in large, multi-ethnic general populations (http://gnomad.broadinstitute.org). At least one other missense variant at this codon is considered to be pathogenic or likely pathogenic, suggesting this variant may also cause disease. This variant segregates with disease in multiple families. Assessment of experimental evidence suggests this variant results in abnormal protein function. A study in mouse embryonic fibroblasts showed this variant caused significant decrease of mtDNA content and completely fragmented the mitochondrial network (PMID: 30293569). The variant is located in a region that is considered important for protein function and/or structure.
