Fig. 4From: Clinical and molecular characterization of three patients with Hepatocerebral form of mitochondrial DNA depletion syndrome: a case seriesa Family III pedigree and sequence chromatograms. Both parents are heterozygous and the affected proband is homozygous for this stop-gain mutation in MPV17 gene. The proband is marked by an asterisk. b Comparative amino acid alignment of MPV17 protein across different kingdoms. The conserved glutamine residue is shown in the box. c Protein structure was predicted by I-TASSER server for 3D protein structure prediction. The secondary structure of protein is changed as a result of the mutation. The deleted region is showed in pinkBack to article page
