Single channel recordings revealed sodium channel reopenings, similar to the gating abnormality of human myotonic muscular dystrophy, which resulted in distrofoa plateau of sodium current. There was also diffuse thickening of the skull with ossification of the falx. Myotonic patients also showed significantly more cortical atrophy than did controls. Arch Dis Child, 67pp. Cardiac Features Hawley et al.

Familial antecedents, severe hypotony or respiratory distress in the neonate are suggestive of the congenital form of myotonic dystrophy. These changes occurred in mice between 3 and 7 months of age.

Delaporte concluded that the personality disorders were not attributable to the adjustment to a disabling condition, but rather were primary manifestations of the genetic mutation. Congenital myotonic dystrophy [abstract]. This segment, which presumably contained the DM gene, was extensively characterized. From study of a single large kindred, Distrlfia et al.


Prolongation of the PR interval can progress to heart block, requiring placement of a pacemaker. Clinical evidence for heterogeneity in myotonic dystrophy.

Genetics and linkage relationships of the C3 polymorphism: A distorfia body of evidence was interpreted as indicating a generalized defect of cell membranes in myotonic dystrophy Butterfield et al.

Periodic ophthalmoscopy is needed to assess posterior capsular cataracts, which may require extraction if vision is impaired significantly–rarely before the third or fourth decade.

Lesions were symmetric, occurred in the subcortical white matter, and showed a predilection for the temporal lobe.

A muscleblind knockout model for myotonic dystrophy. Lancet,pp. However, MYH14 retained normal subcellular localization in DM1 patient muscle, albeit at lower amounts than in controls.

Neonatal myotonic dystrophy as a cause of hydramnios and neonatal death.

Mouse tissue culture models of unstable triplet repeats: Anticipation resulting in elimination of the myotonic dystrophy gene: This suggested to Leeflang et al. These results suggested to Sarkar et al. Ultrasound Obstet Gynecol, 20pp. Charles C Thomas pub. Ultrastructural studies show dilatation of Miotonoca tubules or sarcoplasmic reticulum, whose contents may be unusually dense Milhaud et al.


There is impaired responsiveness to follicle stimulating hormone with hypogonadism Sagel et al. Therefore, it seemed highly probable that the DM gene would be eliminated from this pedigree within 1 generation. The diagnosis was supported by an autosomal dominant miotojica pattern and by features of muscle histopathology consistent with DM.

Di Chiro and Caughey reviewed radiographic findings in the skull in 18 cases. CTG-Expansion Effects on Chromosome Structure The mechanism by which the expanded trinucleotide repeat in the 3-prime untranslated region of the DMPK gene leads to the clinical features is unclear.

J Med Genet, 29pp. With the observations of Cobo et al. Cis and trans effects of the myotonic dystrophy DM mutation in a cell culture model. Linkage studies by Cobo et al.
