Vascular skin disorders
Gene: F12After NHS Genomic Medicine Service consideration, the mode of inheritance of this gene has not been changed and remains 'BOTH monoallelic and biallelic, autosomal or pseudoautosomal'.Created: 31 Jan 2023, 4:29 p.m. | Last Modified: 31 Jan 2023, 4:29 p.m.
Panel Version: 1.50
This gene will be flagged for GMS review regarding the pertinence of monoallelic variants to this panel and whether the MOI should remain as 'both mono- and biallelic' or changed to 'biallelic' only.
Monoallelic variants are associated with hereditary angioedema (MIM# 610618) characterised clinically by recurrent skin swelling but otherwise no other skin phenotypes. Biallelic variants cause a separate disorder, factor XII deficiency (MIM# 234000) associated with hypercoagulation. Skin manifestations may occur in some cases including ulcers and superficial thrombophlebitis in the limbs and trunk.Created: 21 Mar 2022, 2:13 p.m. | Last Modified: 21 Mar 2022, 2:13 p.m.
