Vascular Malformations_Germline v0.115 PIK3CA Zornitza Stark Mode of pathogenicity for gene: PIK3CA was changed from to Loss-of-function variants (as defined in pop up message) DO NOT cause this phenotype - please provide details in the comments
Vascular Malformations_Germline v0.114 PIK3CA Zornitza Stark Mode of inheritance for gene: PIK3CA was changed from to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Vascular Malformations_Germline v0.35 PTPN11 Bryony Thompson gene: PTPN11 was added
gene: PTPN11 was added to Inherited Vascular Malformations. Sources: Expert list
Mode of inheritance for gene: PTPN11 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for gene: PTPN11 were set to 27193571; 24939587; 29907801
Phenotypes for gene: PTPN11 were set to LEOPARD syndrome 1 151100; Noonan syndrome 1 163950; cystic hygroma
Review for gene: PTPN11 was set to GREEN
Added comment: A pathogenic de novo variant was identied in a case diagnosed with megalencephaly-capillary malformation (MCAP) syndrome. However, the cases also had a somatic mosaic variant in PIK3CA which is the usual cause of MCAP. One of the prominent features of Noonan syndrome caused by this gene is cystic hygromas.
