Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Comment on mode of pathogenicity: Activating mutations are indicated in G2P as mutation consequence for noonan syndrome. Comments from reviewer:
Gain of function mutations in RAF1 are reported to cause up to 3% of cases of LEOPARD syndrome. - Helen Savage (Congenica Ltd), Jan. 21, 2016, 11:27 a.m.
Gain of function mutations in RAF1 cause Noonan syndrome and LEOPARD syndrome. These disorders share phenotypes with Legius syndrome. Mutations in RAF1 have not been reported to cause Legius syndrome. - Helen Savage (Congenica Ltd), Jan. 25, 2016, 11:50 a.m.
Gain of function mutations in RAF1 cause ~10% of Noonan syndrome cases and ~1% of LEOPARD syndrome cases. - Helen Savage (Congenica Ltd), Jan. 21, 2016, 2:20 p.m.
