Novel mutation m.14439G>A in Pt377 mtDNA. (A) Trio-sequencing analysis of m.14439G>A (MT-ND6 p.P79S) change in Pt377 family. Sequence chromatograms show that the m.14439G>A is detectable only in Pt377. (B) PCR-RFLPanalysis using fibroblast mtDNA from Pt377 and blood from both parents. A 619-bp PCR fragment was digested with Hpy188I. Wild-type mtDNA was cleaved into two fragments of 333 and 286 bp as shown in “Mother” and “Father”, whereas the PCR product containing the m.14439G>A mutation was cleaved into three fragments: 286, 227, and 106 bp (“Pt377”). Undigested = undigested PCR product. (C) Alignment of MT-ND6 protein between different species shows the conservation of amino acid Proline 79. Amino acid sequences of MT-ND6 gene products were aligned by ClustalW program (http://www.ebi.ac.uk/Tools/msa/clustalw2/) and NCBI/homologene (http://www.ncbi.nlm.nih.gov/homologene).
