Eight new mutations and the expanding phenotype variability in muscular dystrophy caused by ANO5.
2012
Objective: Description of 8 new ANO5 mutations and significant expansion of the clinical phenotype spectrum associated with previously known and unknown mutations to improve diagnostic accuracy. Methods: DNA samples of 101 patients in 95 kindreds at our quaternary referral center in Finland, who had undetermined limb-girdle muscular dystrophy (LGMD), calf distal myopathy, or creatine kinase (CK) elevations of more than 2,000 IU/L, were selected for ANO5 genetic evaluation, and the clinical findings of patients with mutations were retrospectively analyzed. Results: A total of 25 patients with muscular dystrophy caused by 11 different recessive mutations in the ANO5 gene were identified. The …
Tachykinergic neurotransmission is enhanced in duodenum from dystrophic (mdx) mice
2005
1 Duodenal longitudinal muscle of mdx mice, an animal model for Duchenne muscular dystrophy, showed a decrease in the electrically evoked nonadrenergic, noncholinergic (NANC) inhibitory responses associated with a reduction of the participation of nitric oxide (NO). In this study, we investigated whether the impairment of NO could also lead to alterations in the NANC excitatory transmission. 2 Nerve-evoked responses consisted of an inhibitory phase followed, at the end of stimulation, by an excitatory response characterised by an increase in amplitude of the spontaneous contractions. In mdx mice, the amplitude of the nerve-evoked contractions was significantly higher than in normals. 3 N(om…
