Abstract/OtherAbstract:
The LEOPARD syndrome is a complex of multisystemic congenital abnormalities characterized by lentiginosis, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonary stenosis, abnormalities of genitalia, retardation of growth, and deafness (sensorineural). Mutations in PTPN11, a gene encoding the protein tyrosine phosphatase SHP-2 located on chromosome 12q24.1, have been identified in 88% of patients with LEOPARD syndrome. A missense mutation (836-->G; Tyr279Cys) in exon 7 of PTPN11 gene was identified in this patient and his mother with LEOPARD syndrome. This mutation is one of the two recurrent mutations most often associated with the syndrome. Leukemia has not previously been reported in patients with LEOPARD syndrome. The authors describe a 13-year-old boy diagnosed with both LEOPARD syndrome and acute myelomonocytic leukemia (AML-M4).
