Affymetrix SNP array data for Genomic Instability and Myelodysplasia with Monosomy 7

ABSTRACT: Gene modified autologous hematopoietic stem cells (HSC) can provide significant clinical benefits to patients suffering from X-linked chronic granulomatous disease (X-CGD), a rare inherited immunodeficiency characterized by recurrent, often life threatening bacterial and fungal infections. Here we report on the molecular and cellular events observed in two patients treated by gene therapy in 2004. After the initial resolution of bacterial and fungal infections, both patients exhibited silencing of transgene expression due to methylation of the viral promoter, and myelodysplasia with monosomy 7 as a result of insertional activation of EVI1. One patient died from overwhelming sepsis 27 months after gene therapy, whereas a second patient underwent an allogeneic HSC transplantation. Our data
