OBJECTIVE To determine the frequency of mutations in CDKL5 in both male and female patients with infantile spasms or early onset epilepsy of unknown cause, and to consider whether the breadth of the reported phenotype would be extended by studying a different patient group. METHODS Two groups of patients were investigated for CDKL5 mutations. Group 1(More)
Genome-wide association studies (GWAS) have identified ten loci harboring common variants that influence risk of developing colorectal cancer (CRC). To enhance the power to identify additional CRC risk loci, we conducted a meta-analysis of three GWAS from the UK which included a total of 3,334 affected individuals (cases) and 4,628 controls followed by(More)
Mutations in the CDKL5 gene (also known as STK9) have recently been shown to cause early onset epilepsy and severe mental retardation (ISSX or West syndrome). Patients with CDKL5 mutations sometimes also show features similar to those seen in Rett Syndrome (RTT). We have screened the CDKL5 gene in 94 patients with RTT or a RTT-like phenotype who had tested(More)
It has been proposed that multiple rare variants in numerous genes collectively account for a substantial proportion of multifactorial inherited predisposition to a variety of diseases, including colorectal adenomas (CRA). We have studied this hypothesis by sequencing the adenomatous polyposis coli (APC) gene in 691 unrelated North American patients with(More)
Inherited factors account for around one third of all colorectal cancers (CRCs) and include rare high penetrance mutations in APC, MSH2, MSH6, and POLE. Here, we sought novel tumor-suppressor genes that predispose to CRC by exome resequencing 50 sporadic patients with advanced CRC (18 diagnosed ≤35 years of age) at a mean coverage of 30×. To help identify(More)
We report that a subject with Cockayne syndrome type A (CS3BE) was a compound heterozygote for mutations in CKN1, the gene encoding the CSA protein (MIM 216400). CS3BE displayed a novel missense mutation (A160V) and a previously described nonsense mutation (E13X). Although residing between the second and third WD-40 repeats characteristic of the CSA(More)
BACKGROUND MUTYH-associated polyposis (MAP) is a recessive trait characterised by multiple colorectal adenomas and a high risk of colorectal cancer. MUTYH functions in the DNA base excision repair pathway and has a key role in the repair of oxidative DNA damage. OBJECTIVES To assess the contribution of inherited variants in genes involved in base excision(More)
Tuberous sclerosis complex (TSC) is caused by mutations in either the TSC1 or TSC2 gene. Both genes are generally considered to act as tumor suppressors that fulfill Knudson's "two-hit hypothesis" and that function within the phosphoinositide 3-kinase-Akt-mammalian target of rapamycin (mTOR) pathway. We previously generated Tsc1(+/-) mice that are(More)
Genome-wide scans have implicated several susceptibility loci, but linkage of 19p13 (IBD6) to Crohn's disease (CD) has not been fully replicated. We report a replication study of IBD6 in a UK Caucasian population. Two hundred eighty-four affected sibling pairs from 234 families were used for the linkage study. Linkage between IBD6 linkage and CD was(More)
BACKGROUND AND AIM To identify the distribution and explore the relationship between ACTN3 genotypes and power and body composition phenotypes. SUBJECTS AND METHODS Case control and association studies were employed using a homogeneous group of players (n = 102) and a control group (n = 110). Power-related phenotypes were measured using the counter(More)
