Human induced pluripotent stem cells generated from Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome patients with a homozygous mutation in the PSMB8 gene (NIHTVBi016-A, NIHTVBi017-A, NIHTVBi018-A).

We have successfully generated induced pluripotent stem cells (iPSC) from dermal fibroblasts and peripheral blood mononuclear cells from patients with a homozygous missense mutation in the gene encoding PSMB8. Biallelic loss of function mutations in this gene are responsible for the PSMB8 deficiency termed Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE). The iPSC carrying the homozygous PSMB8 gene mutation (c.224C > T, T75M) are phenotypically normal and have the capacity to differentiate toward the three germ layers. These iPSC have great potential to study the role of PMSB8 in the regulation of immune responses and other cellular pathways.
