Waardenburg syndrome type 1 (WS1), a rare genetic disease characterized by pigmentation defects and mild craniofacial anomalies often associated with congenital deafness is caused by heterozygous mutations in the PAX3 gene (2q36.1). We have generated two induced pluripotent stem cell lines (PCli029-A and PCli031-A) from two patients from the same family both carrying the same heterozygous deletion in PAX3 exon 1 (c.-70_85 + 366del). These cells are pluripotent as they can differentiate into ectoderm, mesoderm and endoderm. They also can activate the early neural crest marker SNAI2. These cells will be useful for studying the human neural crest-derived pigment cells.
