Interindividual variation in mean leukocyte telomere length (LTL) is associated with cancer and several age-associated diseases. We report here a genome-wide meta-analysis of 37,684 individuals with replication of selected variants in an additional 10,739 individuals. We identified seven loci, including five new loci, associated with mean LTL (P < 5 ×(More)
OBJECTIVES There are numerous indications that genetic factors play an important role in the pathogenesis of osteoporosis, a common condition characterized by reduced bone mass and increased fracture risk. The vitamin D receptor (VDR) gene has been suggested as a possible candidate gene for the regulation of bone mass but the relationship between VDR(More)
Cytotoxic T lymphocyte-associated protein 4 (CTLA-4) and inducible T-cell co-stimulator (ICOS) genes are important mediators of T-cell activation in autoimmune diseases. The aim of the current study was to assess the impact of CTLA-4 and ICOS genes on the susceptibility to type 1 diabetes among two populations with different disease incidence rates. Three(More)
Inherited ataxias are clinically and genetically heterogeneous, and a molecular diagnosis is not possible in most patients. Having excluded common sporadic, inherited and metabolic causes, we used an unbiased whole exome sequencing approach in 35 affected individuals, from 22 randomly selected families of white European descent. We defined the likely(More)
BACKGROUND Behr's syndrome is a classical phenotypic description of childhood-onset optic atrophy combined with various neurological symptoms, including ophthalmoparesis, nystagmus, spastic paraparesis, ataxia, peripheral neuropathy and learning difficulties. OBJECTIVE Here we describe 4 patients with the classical Behr's syndrome phenotype from 3(More)
Whole exome sequencing (WES) is a recently developed technique in genetics research that attempts to identify causative mutations in complex, undiagnosed genetic conditions. Causative mutations are usually identified after filtering the hundreds of variants on WES from an individual's DNA selected by the phenotype. We investigated a patient with a slowly(More)
The protein tyrosine phosphatase nonreceptor type 22 (PTPN22) gene is expressed in hematopoietic tissue and peripheral blood mononuclear cells including natural killer (NK) cells. The rs2476601 single nucleotide polymorphism (SNP) in the PTPN22 gene is an important susceptibility marker for autoimmunity but its role in NK cell biology is not yet clear. The(More)
Protein tyrosine phosphatase non-receptor type 22 (PTPN22) is considered an important regulator of T-cell activation. Polymorphisms within the PTPN22 gene have been suggested to confer susceptibility to autoimmune endocrine disorders. To evaluate the impact of a functional variation in the PTPN22 gene in type 1 (T1D) and type 2 diabetes (T2D), the PTPN22(More)
Mutations in the transient receptor potential vanilloid 4 (TRPV4) gene have been associated with autosomal dominant skeletal dysplasias and peripheral nervous system syndromes (PNSS). PNSS include Charcot-Marie-Tooth disease (CMT) type 2C, congenital spinal muscular atrophy and arthrogryposis and scapuloperoneal spinal muscular atrophy. We report the(More)
