Human iPSC lines from a Christianson syndrome patient with NHE6 W523X mutation, a biologically-related control, and CRISPR/Cas9 gene-corrected isogenic controls.

Loss-of-function mutations in Na+/H + exchanger 6 (NHE6) (also termed SLC9A6) cause the X-linked neurogenetic disorder Christianson syndrome (CS). Using peripheral blood mononuclear cells, we developed induced pluripotent stem cell (iPSC) lines from a patient with the NHE6 nonsense mutation c.1569G > A (p.(W523X)) and diagnosed with CS and from a biologically-related control. Using CRISPR/Cas9 gene editing, we generated two isogenic control lines in which the c.1569G > A mutation was corrected. All lines were verified by DNA sequencing and for NHE6 protein expression, pluripotency, and differentiation potential. These lines will serve as a valuable resource for both basic and translational studies in CS.
