The m.11467A>G (p.L236L) variant in MT-ND4 was reviewed by the Mitochondrial Disease Nuclear and Mitochondrial Variant Curation Expert Panel on January 13, 2025. This variant has not been reported in the medical literature as causative in affected individuals or families with primary mitochondrial disease to our knowledge. This variant is present at high frequencies in population databases (13% of individuals in MITOMAP, 16% in gnomAD v3.1.2, and 20% in the Helix dataset; BA1). Furthermore, this variant is a marker for European haplogroups U and K, where it is found at >99%, however the presence of this variant in an individual with primary mitochondrial disease outside of haplogroups U and K may warrant further consideration to rule out any detrimental effect of the variant. There are no in silico predictors for this type of variant in mitochondrial DNA. There are no cybrids, single fiber studies, or other functional assays reported on this variant. In summary, this variant meets criteria to be classified as benign for primary mitochondrial disease inherited in a mitochondrial manner. This classification was approved by the NICHD/NINDS U24 ClinGen Mitochondrial Disease Variant Curation Expert Panel on January 13, 2025. Mitochondrial DNA-specific ACMG/AMP criteria applied (PMID: 32906214): BA1.
