Frequency of myotonic dystrophy gene carriers in cataract patients.
DNA samples from 231 unselected patients with cataracts were studied to determine the frequency of the DM mutation in cataract patients. A previous epidemiological study established a high prevalence of DM in the population of Guipúzcoa (Basque Country, Spain), 26.5 cases/100,000. We have found two carriers (0.9%) of the DM mutation in patients who are not related to any previously known DM fam...
متن کاملGenotype–Phenotype Correlations in Iranian Myotonic Dystrophy Type I Patients
Objectives: Myotonic Dystrophy type I (DM1) is a dominantly inherited disorder with a multisystemic pattern affecting skeletal muscle, heart, eye, endocrine and central nervous system. DM1 is associated with the expansion and instability of CTG repeat in the 3chr('39') untranslated region of the myotonic dystrophy protein kinase (DMPK) gene located on chromosome 19q13.3. The aim of this study w...
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 کاملAscertainment of myotonic dystrophy through cataract by selective screening.
Myotonic dystrophy (DM) almost always results from the expansion of an unstable (CTG)n repeat. The mutation can be detected directly. Affected patients with cataracts may have minimal additional signs of the disorder, but all are at risk of life threatening complications. We have studied the efficacy of detecting new families with myotonic dystrophy by selectively screening cataract patients. S...
متن کاملFuchs' Endothelial and Myotonic Dystrophies: Corneal Dystrophy in Myotonic Patients.
We read with great interest the article by Mootha et al. concerning a possible correlation between Fuchs’ endothelial corneal dystrophy (FECD) and myotonic dystrophy (MD). We thank the authors because, among the studies we made trying to understand the reason of low intraocular pressure in patients with MD, they cited one study we published in 2010 where we examined the endothelial cells charac...
