PTPN11 gene mutation associated with abnormal gonadal determination.

Abstract excerpt

Germline mutations in the PTPN11 gene have been associated with Noonan syndrome (NS) and LEOPARD syndrome. Both germline and somatic mutations in this gene have been reported in association with malignancies. However, the T507K mutation in the PTPN11 gene, has only been reported in malignancies and in a fetus with hydrops fetalis but not in a live patient with NS. We report the autopsy findings in a fetus with...
