We report here that individuals with Noonan syndrome and juvenile myelomonocytic
leukemia (JMML) have germline mutations in PTPN11 and that somatic mutations in
PTPN11 account for 34% of non-syndromic JMML. Furthermore, we found mutations in
PTPN11 in a small percentage of individuals with myelodysplastic syndrome (MDS) and de
novo acute myeloid leukemia (AML). Functional analyses documented that the two most
common mutations in PTPN11 associated with JMML caused a gain of function.
