Summaries for Spinal Muscular Atrophy, Type I

NIH Rare Diseases : 53 Spinal muscular atrophy 1 (SMA1), also known as Werdnig Hoffmann disease, is a genetic neuromuscular disorder that affects the nerve cells that control voluntary muscles (motor neurons). Without treatment, 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 (pathogenic variants also called mutations) in the SMN1 gene and is typically inherited in an autosomal recessive manner. Diagnosis of SMA1 is suspected by symptoms and confirmed by genetic testing. SMA has been added to the list of recommended newborn screening tests in the United States, so that it can be detected prior to symptoms developing. This occurred because treatments are being developed that are changing the course of the disease. In December 2016, nusinersen (Spinraza) became the first FDA approved treatment for SMA1. Continued treatment with nusinersen is allowing many babies with SMA1 to reach and maintain age appropriate developmental milestones, including sitting, crawling, and walking. On average, breathing problems, nutrition problems, and hospital admissions have also decreased. However, response to treatment does vary. Some babies with SMA1 may not respond to the nusinersen at all or may have medical complications that prevent use of the treatment. Other treatments remain supportive.

MalaCards based summary : Spinal Muscular Atrophy, Type I, also known as werdnig-hoffmann disease, is related to spinal muscular atrophy, distal, autosomal recessive, 1 and spinal muscular atrophy, type ii. An important gene associated with Spinal Muscular Atrophy, Type I is SMN1 (Survival Of Motor Neuron 1, Telomeric), and among its related pathways/superpathways is TP53 Regulates Metabolic Genes. The drugs Hydroxyurea and Valproic Acid have been mentioned in the context of this disorder. Affiliated tissues include spinal cord, brain and testes, and related phenotypes are respiratory insufficiency and recurrent respiratory infections

OMIM : 57 Spinal muscular atrophy refers to a group of autosomal recessive neuromuscular disorders characterized by degeneration of the anterior horn cells of the spinal cord, leading to symmetrical muscle weakness and atrophy (summary by Wirth, 2000). Four types of SMA are recognized depending on the age of onset, the maximum muscular activity achieved, and survivorship: type I, severe infantile acute SMA, or Werdnig-Hoffman disease; type II (253550), or infantile chronic SMA; type III (253400), juvenile SMA, or Wohlfart-Kugelberg-Welander disease; and type IV (271150), or adult-onset SMA. All types are caused by recessive mutations in the SMN1 gene. Lunn and Wang (2008) provided a detailed review of clinical features, molecular pathogenesis, and therapeutic strategies for SMA. (253300)

NINDS : 54 Spinal Muscular Atrophy (SMA) Types I, II, and III belong to a group of hereditary diseases that cause weakness and wasting of the voluntary muscles in the arms and legs of infants and children. The disorders are caused by an abnormal or missing gene known as the survival motor neuron gene 1 (SMN1), which is responsible for the production of a protein essential to motor neurons. Without this protein, lower motor neurons in the spinal cord degenerate and die. The type of SMA (I, II, or III) is determined by the age of onset and the severity of symptoms. Type I (also known as Werdnig-Hoffman disease, or infantile-onset SMA) is evident at birth or within the first few months. Symptoms include floppy limbs and trunk, feeble movements of the arms and legs, swallowing and feeding difficulties, and impaired breathing. Type II (the intermediate form) usually begins 6 and 18 months of age. Legs tend to be more impaired than arms. Children with Type II may able to sit and some may be able to stand or walk with help. Symptoms of Type III (also called Kugelberg-Welander disease) appear between 2 and 17 years of age and include difficulty running, climbing steps, or rising from a chair.  The lower extremities are most often affected.  Complications include scoliosis and chronic shortening of muscles or tendons around joints.  

UniProtKB/Swiss-Prot : 75 Spinal muscular atrophy 1: A form of spinal muscular atrophy, a group of neuromuscular disorder characterized by degeneration of the anterior horn cells of the spinal cord, leading to symmetrical muscle weakness and atrophy. Autosomal recessive forms are classified according to the age of onset, the maximum muscular activity achieved, and survivorship. The severity of the disease is mainly determined by the copy number of SMN2, a copy gene which predominantly produces exon 7-skipped transcripts and only low amount of full-length transcripts that encode for a protein identical to SMN1. Only about 4% of SMA patients bear one SMN1 copy with an intragenic mutation. SMA1 is a severe form, with onset before 6 months of age. SMA1 patients never achieve the ability to sit.
