Werdnig-Hoffmann Type of Spinal Muscular Atrophy

Acute Werdnig-Hoffmann disease: acute infantile spinal muscular atrophy.

Prenatal diagnosis of spinal muscular atrophy type I (Werdnig- hoffmann) by DNA deletion analysis of cultivated amniocytes.

AIM Presentation of a prenatally diagnosed case of Werdnig-Hoffmann disease, the most severe type of spinal muscular atrophy. METHODS DNA obtained from cultivated amniocytes was analyzed for deletions in the survival motor neuron gene and neuronal apoptosis inhibitory protein gene. RESULTS The fetus was diagnosed as an affected homozygote for deletions in exon 7 and exon 8 of the survival m...

Spinal Muscular Atrophy: A Short Review Article

Spinal muscular atrophy (SMA) is a genetic disorder which affect nervous system and is characterized with progressive distal motor neuron weakness. The survival motor neuron (SMN) protein level reduces in patients with SMA. Two different genes code survival motor neuron protein in human genome. Skeletal and intercostal muscles denervation lead to weakness, hypotony, hyporeflexia, respiratory fa...

Chronic spinal muscular atrophy of facioscapulohumeral type.

Chronic spinal muscular atrophy of FSH type affecting a mother and her son and daughter is reported. The relevant literature is reviewed and the relation between this conditon and Kugelberg-Welander (K-W) disease is discussed. Chronic spinal muscular atrophy of FSH type is considered to be a different entity from the eponymous K-W disease. Each type of muscular dystrophy, e.g. limb-girdle, FSH,...

Chronic generalized spinal muscular atrophy of infancy and childhood. Arrested Werdnig-Hoffman disease.

Pearn, J. H., and Wilson, J. (1973). Archives of Disease in Childhood, 48, 768. Chronic generalized spinal muscular atrophy of infancy and childhood: arrested Werdnig-Hoffmann disease. Recent studies have shown that the acute fatal form of infantile spinal muscular atrophy (acute Werdnig-Hoffmann disease or spinal muscular atrophy Type I) is a distinct genetic and clinical entity. This has prom...
