Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000155642 SCV000205350 likely pathogenic Noonan syndrome 2015-12-14 criteria provided, single submitter clinical testing The p.Gln367Lys variant in CBL has been identified by our laboratory in 1 indivi dual with clinical features of Noonan syndrome and segregated with disease in 3 affected relatives. It was absent from large population studies. Two other amino acid changes at this position (p.Gln367Pro, p.Gln367Arg) have been reported: 1 in an individual with Noonan syndrome (Martinelli 2010) and 1 in an individual w ith chronic myelomonocytic leukemia (CMML; Kholmann 2010). Missense variants in exon 8 are located in the linker domain of CBL, are mutational hotspots in hemat ological malignancies, and have been shown to affect CBL protein function in bot h in vivo and in vitro studies (Sanada 2009, Martinelli 2010). Additional comput ational prediction tools and conservation analysis suggest that the p.Gln367Lys variant may impact the protein. In summary, although additional studies are requ ired to fully establish its clinical significance, the p.Gln367Lys variant is li kely pathogenic.
