MT-ATP6 and Leigh syndrome: Otherwise, our reporting is not in accordance with other studies that have observed susceptibility of Leigh disease on other haplogroups rather than haplogroup H, such as N9a, B5 and Y in Chinese patients [106,107], and haplogroup U5b on mutant cell lines [108]; all are descended from the macro-haplogroup N. Asian haplogroup M is also reported in another Indian Leigh case as harbouring m.8936T>A in the MT-ATP6 gene [109].
