Myotonic dystrophy (DM) is an autosomal dominant disease which, in the typical pedigree, shows a three generation anticipation cascade. This results in infertility and congenital myotonic dystrophy (CDM) with the disappearance of DM in that pedigree. The concept of segregation distortion, where there is preferential transmission of the larger allele at the DM locus, has been put forward to expl...

SYNOPSIS A case of myotonic dystrophy accompanied by alveolar hypoventilation and hypersomnia is presented. Radiological studies and EMG examination of the intercostal muscles demonstrated that the respiratory muscles were affected by the disease, while polygraphic recordings showed that the alveolar hypoventilation and pulmonary hypertension worsened during sleep. The hypersomnia preceded the ...
متن کاملOcular motor myotonic phenomenon in myotonic dystrophy.
OBJECTIVE To detect disconjugate ocular motor abnormalities and a possible extraocular muscle myotonic phenomenon in patients with myotonic dystrophy (MyD). METHODS The magnetic scleral search coil technique was used to record monocularly the small (25 degrees ) and large (50 degrees ) saccades, which were paced to two interstimulus intervals (ISIs), one short (1 s), the other long (5 s). The...
