The second is that of juvenile spinal amyotrophy resembling Kugelberg-Welander’s syndrome. In the juvenile form type 2onset is between ages 2 and 6 with locomotor ataxia, behavioural disorders, and progressive loss of intellectual capacities, leading to a state of decerebration and death at around the age of The enzyme activator required for hydrolysing GM2 is deficient.

Inhibition of myostatin does not ameliorate disease features of severe spinal muscular atrophy mice. TEXT A number sign is used with this entry because the Finkel type of late-onset autosomal dominant spinal muscular atrophy SMAFK is caused by heterozygous mutation in the gene encoding vesicle-associated membrane protein-associated protein B VAPB; on chromosome 20q The first is similar to atypical Friedreich disease, with spinocerebellar ataxia but no cardiac or osseous signs, such as scoliosis or flat feet.

Disease definition GM2 gangliosidosis, variant B or Tay-Sachs disease is marked by accumulation of G2 gangliosides due to hexosaminidase A deficiency. The disorder degenerates into a state of decerebration and is fatal during childhood. Standard Therapies Treatment Treatment of Kugelberg-Welander syndrome enfermedd aimed at alleviating the symptoms. CC HPO: Genetic counseling may be of benefit for patients and their families.



In most cases physical therapy and orthopedic devices may be prescribed. A mutation in the vesicle-trafficking protein VAPB causes late-onset spinal muscular atrophy and amyotrophic lateral sclerosis.

All studies receiving U. In a study on the classification and genetics of proximal SMA, Zerres documented the clinical course of 6 families including 20 patients suffering from an autosomal dominant form.

Molecular genetic testing is used to determine if a mutation is present in the SMN gene. J Med Genet ; Cunha MC, et al. Andersson PB, kugelberg-welanfer al. Duchenne muscular dystrophy is initially characterized by muscle weakness within the pelvic area that may be followed by involvement of the shoulder muscles.

Treatment Treatment of Kugelberg-Welander syndrome is aimed at alleviating the symptoms. Three families were classified as having the adult-onset form after age 20 years. Causes All types of proximal spinal muscular atrophy SMA including Kugelberg Welander syndrome are caused by mutations nefermedad the SMN survival motor neuron gene at chromosomal locus 5qq In a fourth family, affected individuals presented with an unusually mild SMA with muscle cramps Ricker and Moxley, ; see They identified the same mutation in another 3 families with ALS8 and in 1 family in which some patients had typical, and others atypical, ALS.

The causative gene Endermedad encodes the alpha subunit of hexosaminidase A and is located on chromosome 15 15q Genetic homogeneity between acute and chronic forms of spinal muscular atrophy. The latter had an onset between ages 17 and 28 years and were only moderately handicapped when examined at ages 38 to 60 years.

J Bone Joint Surg Am ; Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted. Retrospective multicenter analysis of patients with SMA assessed between and There is no efficient treatment for Tay-Sachs disease, but anti-epileptics can be prescribed. Two variants of the disease have been reported.
