Supravalvular aortic stenosis (SVAS) is a congenital narrowing of the ascending aorta which can occur sporadically, as an autosomal dominant condition, or as one component of Williams syndrome. SVAS is caused by translocations, gross deletions and point mutations that disrupt the elastin gene (ELN) on 7q11.23. Functional hemizygosity for elastin is known to(More)
BACKGROUND Mutations in the PRSS1 gene explain most occurrences of hereditary pancreatitis (HP) but many HP families have no PRSS1 mutation. Recently, an association between the mutation N34S in the pancreatic secretory trypsin inhibitor (SPINK1 or PSTI) gene and idiopathic chronic pancreatitis (ICP) was reported. It is unclear whether the N34S mutation is(More)
Hereditary pancreatitis (HP) is usually caused by mutations in the cationic trypsinogen (PRSS1) gene, especially R122H or N29I. We sequenced the PRSS1 gene in the proband of families without these common mutations. Novel R122C and N29T mutations were detected in independent families that segregated with the disease in an autosomal dominant fashion. The(More)
This article highlights several of the important issues and illustrates a European protocol that should be considered when offering genetic testing on a research or clinical basis for HP, as well as for other inherited disorders of the pancreas.
BACKGROUND Life course research methodologies are used extensively in historical and social science research. In 1998 the life course paradigm was introduced to provide a way of tracing the interplay of person and setting. The method has had a very limited use in nursing research, but in this study it was utilized as a way of capturing dynamic change by(More)
Goldberg-Shprintzen syndrome is a rare autosomal recessive condition that describes the association of Hirschsprung disease with microcephaly, developmental delay and characteristic facies. We describe two brothers from a non-consanguineous family who have classical features of Goldberg-Shprintzen syndrome. The novel findings in this instance are of foot(More)
Tay-Sachs disease is a lethal neurodegenerative disorder caused by deficiency of the lysosomal enzyme beta-hexosaminidase A and inherited in an autosomal recessive fashion; carriers of the disease are 10 times more frequent in the Ashkenazi Jewish community than in the general population. Over 90% of North American Ashkenazi carriers tested have been shown(More)
The prevalence of pancreatic cancer in the general population is too low--even in high-prevalence areas such as Northern Europe and North America (8-12 per 10(5) population)--relative to the diagnostic accuracy of present detection methods to permit primary screening in the asymptomatic adult population. The recognition that the lifetime risk of developing(More)
OBJECTIVES To explore genetics professionals' and patients' views about which outcome domains are most appropriate to measure the patient benefits of using a clinical genetics service. METHODS A postal Delphi survey was sent to: 115 consultant geneticists; 162 genetic counsellors; 156 support group representatives; 106 patients. The survey contained 19(More)
