Sialidosis type I is caused by mutations in the NEU1 gene. Individuals with sialidosis type I have mutations that result in some functional NEU1 enzyme. The condition is inherited in an autosomal recessive pattern. It does not affect intelligence or life expectancy.Sialidosis is a severe inherited disorder that affects many organs and tissues, including the nervous system. This disorder is divided into two types, which are distinguished by the age at which symptoms appear and the severity of features. Sialidosis type I is the less severe form of this condition.
