Generation of an iPSC cohort of isogenic iPSC lines (46-XY and 47-XXY) from a non-mosaic Klinefelter Syndrome patient (47-XXY) (KAUSTi008-A, KAUSTi008-B, KAUSTi008-C, KAUSTi008-D, KAUSTi008-E, KAUSTi008-F, KAUSTi008-G)

Abstract

Klinefelter Syndrome (KS) is the most common X chromosome aneuploidy in males characterized by highly heterogeneous clinical manifestations including a subtle cognitive impairment and multisystemic disorders such as infertility, metabolic syndrome, gynecomastia and cardiovascular diseases. To date dosage-dependent correlation studies of X-linked genes and low- and high-grade KS clinical phenotypes have not been performed. Here we generated multiple isogenic 47-XXY and 46-XY iPSC lines from one 47-XXY patient. Leveraging on a fully matched genetic background, our cohort represents a highly informative tool to study the impact of X chromosome dosage on KS pathophysiology.
