Figure. Pedigrees of patient 1 and 2, partial Sanger chromatograms, amino acid conservation, and homology modeling
(A) Pedigree structure of the family of patient 1 (IV-1) with the c.934A>G (M) mutation in TOR1A, demonstrating segregation of the mutation. The proband is indicated by the sign of arrow. (B) Partial chromatogram indicating the c.934A>G mutation in TOR1A in patient 1. (C) Evolutionary conservation of amino acid at position 312, revealing high conservation down to zebrafish. (D) Homology model of the human torsinA p.R312G mutant. The α-helices and β-sheet of the AAA+ domain are colored in blue and purple, respectively. The C-terminal domain is colored in light blue. The ATP molecule and G312 are represented as sticks and colored by CPK. The mutation region is highlighted at the top right of this figure. Image generated with PyMOL (pymol.org/2/). (E) Pedigree structure of the family of patient 2 (II-1) with the c.863G>A (M) mutation in TOR1A. The proband is indicated by the sign of arrow. Three siblings are indicated by diamond (undisclosed sex) symbols. The siblings have not been tested for the mutation. (F) Partial chromatogram indicating the c.863G>A mutation in TOR1A in patient 2. ATP = adenosine triphosphate.
