Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Wilsons disease (WD) is a relevant human genetic disease caused by mutations in the ATP7B gene, whose product is a liver enzyme responsible for copper export into bile and blood. Interestingly, the spectrum of ATP7B mutations is vast and can influence clinical presentation (a variable spectrum of hepatic and neural manifestations), though the reason for this is not well understood. Here we describe the successful generation of iPSCs from a Chinese patient with Wilsons disease that bears the R778L Chinese hotspot mutation in the ATP7B gene.

Description
We have generated iPSCs from monosomy X (Turner Syndrome), trisomy 8 (Warkany Syndrome 2), trisomy 13 (Patau Syndrome) and partial trisomy 11;22 (Emanuel Syndrome), using either skin fibroblasts from affected individuals or amniocytes from antenatal diagnostic tests. These cell lines stably maintain the karyotype of the donors and behave like embryonic stem cells (ESCs) in all tested assays. Turner Syndrome iPSCs were used for further studies including global gene expression analysis and tissue-specific directed differentiation. Multiple clones displayed lower levels of the pseudoautosomal genes ASMTL and PPP2R3B than the controls. Moreover, they could be transformed into neural-like, hepatocyte-like and heart-like cells but displayed insufficient up-regulation of the pseudoautosomal placental gene CSF2RA during embryoid body (EB) formation. These data support that abnormal organogenesis and early lethality in Turner Syndrome are not caused by a tissue-specific differentiation blockade but rather involves other abnormalities including impaired placentation.
