BACKGROUND Duplications and deletions in the human genome can cause disease or predispose persons to disease. Advances in technologies to detect these changes allow for the routine identification of submicroscopic imbalances in large numbers of patients. METHODS We tested for the presence of microdeletions and microduplications at a specific region of(More)
We report a recurrent microdeletion syndrome causing mental retardation, epilepsy and variable facial and digital dysmorphisms. We describe nine affected individuals, including six probands: two with de novo deletions, two who inherited the deletion from an affected parent and two with unknown inheritance. The proximal breakpoint of the largest deletion is(More)
In recent years, the maturation of microarray technology has allowed the genome-wide analysis of gene expression patterns to identify tissue-specific and ubiquitously expressed ('housekeeping') genes. We have performed a functional and topological analysis of housekeeping and tissue-specific networks to identify universally necessary biological processes,(More)
PURPOSE Previous studies did not discriminate wild-type from hemizygous genotypes of GSTM1 and GSTT1. In this study, we investigated wild-type, hemizygous deletion, and homozygous deletion genotypes of GSTM1 and GSTT1 and lung cancer risk. METHODS We conducted a nested case-control study of 143 primary incident lung cancer cases matched to 447 cancer-free(More)
Copy number variations are important polymorphisms that can influence the expression of genes within and close to the rearranged region. This allows transcription levels to be higher or lower than those that can be achieved by control of transcription of a single copy. Recently, copy number variations have been associated with genetic diseases such as(More)
OBJECTIVE Glutathione-S-transferases (GSTs) play an important role in tobacco smoke detoxification, interestingly approximately 50% of individuals in most human populations lack the gene GSTM1 due to copy number variation (CNV). We aimed to investigate GSTM1 CNV in Rheumatoid Arthritis (RA) in relation to smoking and HLA-DRB1 shared epitope; the two best(More)
