Figures

Figure 1-
Figure 1-. identification of TYK2 homozygous mutation
(a) Pedigree of a family in which a homozygous mutation in TYK2 was identified in the index case. Squares and circles denote male (father) and female (mother), respectively. Half-filled square and circle symbolize heterozygous carriers of c.647delC mutation. Living affected and unaffected males show in black and clear squares, respectively. (b) Validation by Sanger sequencing of the TYK2 mutation in the patient, brother and their parents. PCR followed by Sanger sequencing confirmed the deletion of a C in exon 7 (c.647delC) leading to a frameshift and the substitution at position 216 causing proline to be converted to arginine followed by a stop codon 13 amino acids after (p.P216Rfs*14). (c) Schematic representation of the TYK2 protein with the position of mutation reported here.
