[https://www.uniprot.org/uniprot/PTN11_HUMAN PTN11_HUMAN] Defects in PTPN11 are the cause of LEOPARD syndrome type 1 (LEOPARD1) [MIM:[https://omim.org/entry/151100 151100]. It is an autosomal dominant disorder allelic with Noonan syndrome. The acronym LEOPARD stands for lentigines, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonic stenosis, abnormalities of genitalia, retardation of growth, and deafness.<ref>PMID:12058348</ref> <ref>PMID:14961557</ref> <ref>PMID:15389709</ref> <ref>PMID:15520399</ref> <ref>PMID:15121796</ref> <ref>PMID:15690106</ref> <ref>PMID:16679933</ref> Defects in PTPN11 are the cause of Noonan syndrome type 1 (NS1) [MIM:[https://omim.org/entry/163950 163950]. Noonan syndrome (NS) is a disorder characterized by dysmorphic facial features, short stature, hypertelorism, cardiac anomalies, deafness, motor delay, and a bleeding diathesis. Some patients with Noonan syndrome type 1 develop multiple giant cell lesions of the jaw or other bony or soft tissues, which are classified as pigmented villomoduolar synovitis (PVNS) when occurring in the jaw or joints. Note=Mutations in PTPN11 account for more than 50% of the cases. Rarely, NS is associated with juvenile myelomonocytic leukemia (JMML). NS1 inheritance is autosomal dominant.<ref>PMID:11704759</ref> <ref>PMID:11992261</ref> <ref>PMID:12325025</ref> <ref>PMID:12161469</ref> <ref>PMID:12529711</ref> <ref>PMID:12634870</ref> <ref>PMID:12739139</ref> <ref>PMID:12960218</ref> <ref>PMID:12717436</ref> <ref>PMID:15384080</ref> <ref>PMID:15948193</ref> <ref>PMID:19020799</ref> Defects in PTPN11 are a cause of juvenile myelomonocytic leukemia (JMML) [MIM:[https://omim.org/entry/607785 607785]. JMML is a pediatric myelodysplastic syndrome that constitutes approximately 30% of childhood cases of myelodysplastic syndrome (MDS) and 2% of leukemia.

== Publication Abstract from PubMed ==
 +
Protein tyrosine phosphatase SHP2 is an oncogenic protein that can regulate different cytokine receptor and receptor tyrosine kinase signaling pathways. We report here the identification of a novel series of SHP2 allosteric inhibitors having an imidazopyrazine 6,5-fused heterocyclic system as the central scaffold that displays good potency in enzymatic and cellular assays. SAR studies led to the identification of compound 8, a highly potent SHP2 allosteric inhibitor. X-ray studies showed novel stabilizing interactions with respect to known SHP2 inhibitors. Subsequent optimization allowed us to identify analogue 10, which possesses excellent potency and a promising PK profile in rodents.
