Rasopathy gene. https://omim.org/clinicalSynopsis/610733. HCM and stenosis can be a key feature as shown in OMIM.Created: 25 Mar 2019, 4:27 p.m.
Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Comment on mode of pathogenicity: G2P mutation consequence is activating. Comments from Reviewer:
Gain of function mutations in SOS1 cause Noonan syndrome. This disorder shares phenotypes with Legius syndrome, however mutations in SOS1 have not been described in patients with Legius syndrome. - Helen Savage (Congenica Ltd), Jan. 25, 2016, 11:52 a.m. Gain of function mutations in SOS1 cause ~10% of Noonan syndrome cases. - Helen Savage (Congenica Ltd), Jan. 21, 2016, 3:58 p.m.Created: 5 Feb 2016, 12:48 p.m.
Comment on mode of inheritance: Confirmed on G2P and OMIM, and not on imprinted gene list.Created: 5 Feb 2016, 8:25 a.m.
