Presymptomatic diagnosis of myotonic dystrophy.
The discovery of an expanded (CTG)n repeat sequence in myotonic dystrophy (DM) has greatly improved our ability to detect DM gene carriers who have few or none of the classical signs of this disorder. We report here our experience with two such groups of gene carriers. We used a PCR based protocol that should be especially sensitive to small increases in CTG triplet number which might escape de...
متن کاملCataract and myotonic dystrophy: the role of molecular diagnosis.
Myotonic dystrophy (dystrophia myotonica), the commonest and most variable of the muscular dystrophies of adult life, has long been known to be associated with cataract, while slit-lamp examination for specific lens opacities has been one of the principal methods of presymptomatic detection of gene carriers. The recent discovery that the myotonic dystrophy mutation is an unstable DNA sequence, ...
متن کاملInstability versus predictability: the molecular diagnosis of myotonic dystrophy.
J7ournal of MEDICAL GENETICS Editorial Instability versus predictability: the molecular diagnosis of myotonic dystrophy In this issue of the Journal a series of papers assesses the utility of molecular analysis of the mutation within the presumed myotonic dys-trophy (DM) gene in the management of this disorder. A detailed correlation of phenotype and genotype will require larger and more compre...
متن کاملA molecular protocol for diagnosing myotonic dystrophy.
Myotonic dystrophy (DM) is an autosomal dominant genetic disease caused by an unstable CTG repeat sequence in the 3' untranslated region of the myotonin protein kinase gene. The CTG repeat is present 5-30 times in the normal population, whereas DM patients have CTG expansions of 50 to several thousand repeats. The age of onset of the disorder and the severity of the phenotype is roughly correla...
متن کاملMyotonic dystrophy
An unquiet life. Memoirs of a physician and cardiologist. This book is of unusual interest. It is not a history of cardiology in Belfast in the last forty years, though that is touched on in some of its aspects. It is the self-revelation of the remarkable man and physician who revolutionised the practice of cardiology in Belfast, in Ulster, and ultimately the world. He may not have meant it, bu...
