Mondo Description Hereditary sensory and autonomic neuropathy type 7 (HSAN7) is a genetic condition that causes the inability to feel pain, excessive sweating, and gastrointestinal issues. Gastrointestinal issues can cause failure to thrive, painful constipation, and diarrhea. The constipation is due to intestinal dysmotility, where the the muscles and nerves of the digestive system do not move food through the digestive tract like it should. Signs and symptoms of HSAN7 usually appear at birth or during infancy. The inability to feel pain often leads to repeated, severe injuries, including bone fractures and joint dislocations. People with HSAN7 may also heal slowly putting them at risk for further complications, such as infection. Excessive sweating may cause itching. Other features may include partial insensitivity to cold and hot temperatures, mild muscle weakness, and motor skill delays. HSAN7 is not known to affect learning or intelligence. Treatment of HSAN7 aims to prevent injury and treat gastrointestinal and orthopedic problems. HSAN7 is caused by a mutation in the SCN11A gene. People with HSAN7 have a 1 in 2 or 50% chance of passing the condition on to each of their children. This pattern of inheritance is called ' autosomal dominant.'
Uniprot Description A form of hereditary sensory and autonomic neuropathy, a genetically and clinically heterogeneous group of disorders characterized by degeneration of dorsal root and autonomic ganglion cells, and by sensory and/or autonomic abnormalities. HSAN7 is characterized by congenital inability to experience pain resulting in self-mutilations, slow-healing wounds, and multiple painless fractures. mild muscle weakness, delayed motor development, slightly reduced motor and sensory nerve conduction velocities, hyperhidrosis and gastrointestinal dysfunction.
Disease Ontology Description A hereditary sensory neuropathy characterized by insensitivity to pain, mild muscle weakness, delayed motor development, hyperhidrosis and gastrointestinal dysfunction that has material basis in heterozygous mutation in the SCN11A gene on chromosome 3p22.
