Leopard syndrome laboratory findings

Hormonal abnormalities may be revealed in some patients with endocrine system involvement. laboratory studies should include molecular analysis of the PTPN11 and RAF1 genes.

Diagnosis of LEOPARD syndrome is sometimes difficult because of the overlap with Noonan syndrome and neurofibromatosis 1. In these patients, the presence of the disease can be confirmed with a mutation-based diagnosis.

laboratory studies should include molecular analysis of the PTPN11 and RAF1 genes.

low levels of follicle-stimulating hormone, luteinizing hormone, and thyrotropin and elevated levels of 17-hydroxy and 17-ketosteroids have been detected in some patients with endocrine abnormalities.
