Cardiofaciocutaneous syndrome 3 OMIM#615279Created: 25 Mar 2019, 4:30 p.m.
Variants in HGMD associated with Cardio-facio-cutaneous syndrome, Noonan and Costello syndrome. Paediatric onset: Kaski Circ Cardiovasc Genet. 2012;5:317-326.Created: 25 Mar 2019, 4:27 p.m.
Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Variants in this GENE are reported as part of current diagnostic practice
Comment on mode of pathogenicity: Activating mutation consequence in G2P. Reviewer Comments: Gain of function mutations in MAP2K1 are responsible for up to 20% of cases of CFC. - Helen Savage (Congenica Ltd), Jan. 21, 2016, 10:31 a.m. Gain of function mutations in MAP2K1 cause Cardio-Facio-cutanenous syndrome and LEOPARD syndrome. These disorders share phenotypes with Legius syndrome. No reports of mutations in MAP2K1 causing Legius syndrome. - Helen Savage (Congenica Ltd), Jan. 25, 2016, 2:55 p.m. Gain of function mutations predicted to be associated with Noonan syndrome in fetuses with abnormal ultrasound findings (see PMID). Possible rare cause of Noonan syndrome; more commonly associated with Cardio-Facio-Cutaenous syndrome and LEOPARD syndrome. - Helen Savage (Congenica Ltd), Jan. 21, 2016, 2:01 p.m.Created: 5 Feb 2016, 8:55 a.m.
