Department of Pediatrics, University of California, Rm HSE 302 Box 0519, San Francisco, CA 94143, USA
Blood 103:2325-31. 2004..We conclude that SHP-2 is an important cellular PTPase that is mutated in myeloid malignancies. Further investigation is required to clarify how these mutant proteins interact with Ras and other effectors to deregulate myeloid growth... - Functional analysis of leukemia-associated PTPN11 mutations in primary hematopoietic cellsSuzanne Schubbert
Department of Pediatrics, University of California at San Francisco, 513 Parnassus Ave, HSE 302, San Francisco, CA 94143, USA
Blood 106:311-7. 2005..Mutant SHP-2 proteins induce aberrant growth in multiple hematopoietic compartments, which supports a primary role of hyperactive Ras in the pathogenesis of JMML... - The mutational spectrum of PTPN11 in juvenile myelomonocytic leukemia and Noonan syndrome/myeloproliferative diseaseChristian P Kratz
University of California, Room HSE 302 Box 0519, San Francisco, CA 94143, USA
Blood 106:2183-5. 2005..This supports the need to characterize the spectrum of hematologic abnormalities in individuals with NS and to better define the impact of the PTPN11 lesion on the disease course in patients with NS/MPD and JMML... - Acquired PTPN11 mutations occur rarely in adult patients with myelodysplastic syndromes and chronic myelomonocytic leukemiaMignon L Loh
Department of Pediatrics, University of California, San Francisco, CA, USA
Leuk Res 29:459-62. 2005..Here, we investigated contribution of PTPN11 mutations to adult MDS and CMML pathogenesis. Our results indicate that PTPN11 lesions might play a role in adult MDS/CMML pathogenesis but do not represent a major molecular event... - Outcome for children treated for relapsed or refractory acute myelogenous leukemia (rAML): a Therapeutic Advances in Childhood Leukemia (TACL) Consortium studyMatthew F Gorman

Department of Pediatrics, University of California-San Francisco, California 94143-0519, USA
J Am Acad Dermatol 54:S22-7. 2006..The patient died of refractory leukemia and secondary fungal disease.
