Generation of human induced pluripotent stem cell line (CMCi015-A) from a patient with nephronophthisis harboring compound heterozygous loss-of-function variants in the NPHP4 gene

Nephronophthisis, an autosomal recessive ciliopathy, is a rare genetic kidney disorder characterized by progressive tubulointerstitial fibrosis, corticomedullary cyst formation, and progression to end-stage renal disease. Here, we established a human induced pluripotent stem cell (hiPSC) line from peripheral blood mononuclear cells of an 18-year-old female patient with nephronophthisis harboring compound heterozygous variants in the NPHP4 gene. This hiPSC displayed features similar to human embryonic stem cells, including pluripotency-associated markers expression, normal karyotype, and the ability to differentiate into cells representing all three germ layers. The implications of this research extend to the potential development of novel treatments for nephronophthisis.
