Electropherogram of mutation and conservation of the P196T variant. (A) Representative electropherogram of the ITGB6 mutation in an affected member of family AI-23 alongside the wild-type sequence. Arrows indicate the localization of the variant. (B) Conservation of the P196 residue in orthologues (upper) and paralogues (lower). Conserved residues are highlighted.
