In vitro and in-vivo studies using mouse mod els have shown strong evidence that this variant affects the protein (Tarataglia 2003, Loh 2004, Chan 2005, Chan 2009, Yang 2010). Other variants at this positi on (p.Asp61Gly, p.Asp61Ala, p.Asp61Asn, p.Asp61His, p.Asp61Val) were also report ed in multiple patients with Noonan syndrome and/or hematological malignancies ( Tartaglia 2005, Kratz 2005, Bertola 2006, Sakaguchi 2013, Strullu 2014). In summ ary, this variant meets our criteria to be classified as pathogenic for JMML (ww w.partners.org/personalizedmedicine/lmm).
