m.1341C>T in MTRNR1: This variant is not expected to have clinical significance because it has been identified in 3.3% (19/565) human mitochondrial DNA sequenc es of the haplogroup U5b, which is primarily of European descent (http://www.mit omap.org). While it has been identified in 1 Finnish individual with occipital s troke and one control (Finnila 2001), 1 child with encephalopyopathy (Uusimaa 20 04), and 1 Chinese proband with sporadic Creutzfeldt-Jakob disease (Zhang 2015), its frequency indicates that it is more likely to be benign. -
