The RB1 gene mutation detection rate in 1,020 retinoblastoma families was increased by the use of highly sensitive allele specific-PCR (AS-PCR) to detect low-level mosaicism for 11 recurrent RB1 CGA>TGA nonsense mutations. For bilaterally affected probands, AS-PCR increased the RB1 mutation detection sensitivity from 92.6% to 94.8%. Both RB1 oncogenic(More)
BACKGROUND Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant disease exhibiting multifocal vascular telangiectases and arteriovenous malformations. The majority of cases are caused by mutations in either the endoglin (ENG) or activin receptor-like kinase 1 (ALK1, ACVRL1) genes; both members of the transforming growth factor (TGF)-beta(More)
BACKGROUND Retinoblastoma is the childhood retinal cancer that defined tumour-suppressor genes. Previous work shows that mutation of both alleles of the RB1 retinoblastoma suppressor gene initiates disease. We aimed to characterise non-familial retinoblastoma tumours with no detectable RB1 mutations. METHODS Of 1068 unilateral non-familial retinoblastoma(More)
BACKGROUND Hereditary haemorrhagic telangiectasia (HHT) is a genetic disorder present in 1 in 8000 people and associated with arteriovenous malformations. Genetic testing can identify individuals at risk of developing the disease and is a useful diagnostic tool. OBJECTIVE To present a strategy for mutation detection in families clinically diagnosed with(More)
We have analyzed RNA from retinoblastoma patients and unaffected carriers with various RB1 gene mutations to determine the patterns of missplicing and associations with phenotypic expression. Most sequence alterations in or in the neighborhood of conserved splice signals that we tested resulted in simple exon skipping (15 mutations) or intron inclusion (new(More)
Hereditary Hemorrhagic Telangiectasia (HHT) is an autosomal dominant vascular disorder caused by mutations in Endoglin (ENG) or activin receptor-like kinase-1 (ALK1, ACVRL1) genes. We performed molecular characterization in clinically affected probands of 31 HHT families and detected a total of 28 different mutations in the two genes, including four shared(More)
A deletion in the tumor-suppressor gene, RB, discovered by quantitative multiplex PCR, shows low penetrance (LP), since only 39% of eyes at risk in this family develop retinoblastoma. The 4-kb deletion spanning exons 24 and 25 (delta24-25) is the largest ever observed in an LP retinoblastoma family. Unlike the usual RB mutations, which cause retinoblastoma(More)
The Visible Genetics Clipper sequencer is a new platform for automated DNA sequencing which employs disposable MicroCel cassettes and 50 microm thick polyacrylamide gels. Two DNA ladders can be analyzed simultaneously in each of 16 lanes on a gel, after labeling with far-red absorbing dyes such as Cy5 and Cy5.5. This allows a simultaneous bidirectional(More)
A descriptive survey was conducted in Region V-E of the United States to bridge the gap in available information on pain issues in the bleeding disorders population. The aim of this study was to a) determine language used by patients to describe and differentiate acute and persistent pain, b) describe pharmacological and non-pharmacological strategies(More)
UNLABELLED The National Pain Study was a prospective, computer-based, descriptive survey of the pain experience of persons with a bleeding disorder conducted in the United States over a 28 month period from 2007 to 2009. The aim of this study was to (i) determine the language used by patients to describe and differentiate acute and persistent pain, (ii)(More)
