MalaCards based summary: Spinal Muscular Atrophy-1, also known as werdnig-hoffmann disease, is related to spinal muscular atrophy and muscular atrophy, and has symptoms including autosomal recessive inheritance, areflexia and tongue fasciculations. An important gene associated with Spinal Muscular Atrophy-1 is SMA4 (glucuronidase, beta pseudogene), and among its related pathways are RNA transport and Regulation of Glucokinase by Glucokinase Regulatory Protein. The compounds aclarubicin and ribonucleic acid have been mentioned in the context of this disorder. Affiliated tissues include spinal cord, brain and tongue.

NIH Rare Diseases:42 Spinal muscular atrophy 1 (sma1), also known as werdnig hoffmann disease, is a severe type of spinal muscular atrophy. symptoms of sma1 become apparent before 6 months of age and include worsening muscle weakness and poor muscle tone (hypotonia) due to loss of the lower motor neurons in the spinal cord and brain stem. feeding and breathing problems are also present. sma1 is caused by changes (mutations) in the smn1 gene and is typically inherited in an autosomal recessive manner. around 2% of cases are not inherited and are due to new mutations in the affected person. treatment is symptomatic and aims to improve quality of life. last updated: 1/21/2015
