Overview
Leopard syndrome is a rare autosomal dominant,[1] multisystem disease caused by a mutation in the protein tyrosine phosphatase, non-receptor type 11 gene (PTPN11). The disease is a complex of features, mostly involving the skin, skeletal and cardiovascular systems, they may or may not be present in all patients. The nature of how the mutation causes each of the condition's symptoms is not well known, however research is ongoing. Related to Noonan syndrome, Leopard syndrome is caused by a different missense mutation of the same gene. Leopard syndrome may also be called multiple lentigines syndrome, cardiomyopathic lentiginosis, Gorlin's syndrome II, Capute-Rimoin-Konigsmark-Esterly-Richardson syndrome, or Moynahan syndrome. Noonan syndrome is fairly common (1:1000 to 1:2500 live births), and neurofibromatosis 1 (which was once thought to be related to Leopard syndrome) is also common (1:3500), but however no epidemiologic data exists for Leopard syndrome.[2]
