Fig. 3From: Identification of a novel mutation in the KITLG gene in a Chinese family with familial progressive hyper- and hypopigmentationThree-dimensional structure of KITLG. a–c Protein three-dimensional structure overall picture. d–f Partial map of protein three-dimensional structure. e Thr and Asn, as polar, neutral R-based amino acids, became Ile, nonpolar, hydrophobic R-based amino acids. When Thr changed to Ile at position 34, the side chain of Ile 34 changed. f When Asn changed to Ile at position 35, the side chain of Ile 35 changedBack to article page
