Generation of an induced pluripotent stem cell line from a compound heterozygous patient in TK2 gene


Autosomal recessive mutations in Thymidine kinase 2 (TK2) gene cause depletion and multiple deletions in mtDNA which normally lead to fatal and progressive neuromyopathy in infants and children. We have generated an induced pluripotent stem cell (iPSC) line by reprogramming fibroblasts derived from a patient carrying TK2 mutations. New iPSC line pluripotency was evaluated by verifying the expression of pluripotency-related genes and the in vitro differentiation into the three germ layers. This human-derived model will be useful for studying the pathogenic mechanisms triggered by these mutations and for testing therapies in cell types normally affected in patients.
