Mutations in the CRYAB gene, encoding alpha-B crystallin, cause distinct clinical phenotypes including isolated posterior polar cataract, myofibrillar myopathy, cardiomyopathy, or a multisystemic disorder combining all these features. Genotype/phenotype correlations are still unclear. To date, multisystemic involvement has been reported only in kindred(More)
OBJECTIVE To describe the phenotypic spectrum of dysferlin (DYSF) gene mutations (which cause dysferlinopathies, autosomal recessive muscular dystrophies) in patients with a dysferlin protein deficiency. DESIGN Clinical, biological, and pathological data from 40 patients were reviewed. The diagnosis of dysferlinopathy was based on the absence or strong(More)
Inherited neuromuscular disorders (NMD) are chronic genetic diseases posing a significant burden on patients and the health care system. Despite tremendous research and clinical efforts, the molecular causes remain unknown for nearly half of the patients, due to genetic heterogeneity and conventional molecular diagnosis based on a gene-by-gene approach. We(More)
37 children presenting with West's syndrome were studied by computerized tomography scanning. An abnormality consisting of diffuse cerebral atrophy, predominating in the fronto-temporal region, was demonstrated in 30 cases. The abnormality was sometimes associated with calcification (tuberous sclerosis) or malformation (agenesis of the corpus callosum). The(More)
We report a boy, born to healthy first cousin parents, with diffuse hyperpigmentation of the skin and guttate hypomelanotic lesions, photophobia, abnormal hair, developmental delay, and recurrent bronchitis. Skin histology showed pigmentation incontinence with numerous melanophages. Electron microscopy showed a very high number of melanosomes and some(More)
BACKGROUND Charcot-Marie-Tooth disease type 1A (CMT1A) is a hereditary peripheral neuropathy that affects roughly one in 5000 births. No specific therapy currently exists for this degenerative disorder, which is characterised by distal progressive muscle atrophy and sensory loss, although ascorbic acid has been shown to reduce demyelination and improve(More)
