sensorineural hearing loss. Symptoms of HSN1 typically begin during a person's teens or twenties and worsen over time. The condition may be caused by any of several genes, depending on the form of HSN1 a person has. For example, HSN type 1A is caused by mutations in the SPTLC1 gene. All forms of HSN1 are inherited in an autosomal dominant manner. If symptoms are treated properly, the condition does not appear to affect life expectancy.Hereditary sensory neuropathy type 1 (HSN1) is a neurological condition characterized by nerve abnormalities in the legs and feet.
