Relative incidence of cutaneous cysts. Steatocystoma is labeled at right. It is associated with defects in Keratin 17. The condition is inherited in an autosomal dominant manner. This indicates that the defective gene responsible for a disorder is located on an autosome, and only one copy of the defective gene is sufficient to cause the disorder, when inherited from a parent who has the disorder. However, a solitary case can also emerge in a family with no prior history of the disorder due to the occurrence of a mutation (often referred to as a sporadic or spontaneous mutation).
