Cranial meningiomas in 411 neurofibromatosis type 2 (NF2) patients with proven gene mutations: clear positional effect of mutations, but absence of female severity effect on age at onset.

Background: Meningiomas have been reported to occur in approximately 50% of neurofibromatosis type 2 (NF2) patients. The NF2 gene is commonly biallelically inactivated in both schwannomas and meningiomas. The spectrum of NF2 mutations consists mainly of truncating (nonsense and frameshift) mutations.

Are patients with intermediate TPMT activity at increased risk of myelosuppression when taking thiopurine medications?

Unlabelled: Thiopurine S-methyltransferase (TPMT) metabolizes thiopurine medications, including azathioprine and 6-mercaptopurine. Absent TPMT activity (i.e.

Pharmacogenetics education in British medical schools.

Pharmacogenetic tests allow medications to be tailored to individual patients to improve efficacy and reduce drug toxicity. In 2005, the International Society of Pharmacogenomics (ISP) made recommendations for undergraduate medical teaching in pharmacogenetics. We aimed to establish the quantity and scope of this in British medical schools.

Mitochondrial profiling of dog hairs.

In order to make greater use of dog hairs as forensic evidence, we have developed a robust method for duplex amplification of adjacent 306 and 332bp amplicons within the 5' hypervariable region (5' HVR) of the canine mitochondrial control region. In support of this, a 595bp region covering 35 polymorphic sites has been sequenced from the blood of 105 UK dogs. In total, 30 different haplotypes were observed, 13 only once whilst the commonest was seen 14 times; the overall exclusion capacity is 0.
