This gene was suggested by Dr Atsuko Okazaki (Division of Genomic Medicine Research, Medical Genomics Center, National Center for Global Health and Medicine, Tokyo, Japan) to be added to this panel. Comments from Dr Atsuko Okazaki: "Among our ~2000 patients, certain numbers of hypertrophic cardiomyopathy patients have m.3243A>G mutation in MT-TL1 with high heteroplasty rate in the heart. Although reporting mitochondrial DNA mutations with their pathogenicity is always challenging due to the heteroplasty rate in affected organs, I think it might be one possibility to let clinicians know that m.3243A>G is a causative mutation for hypertrophic cardiomyopathy if mutation rate is high in the heart."
