Rare genetic inflammatory skin disorders
Gene: GJB4The mode of inheritance of this gene has been updated to 'MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown' following NHS Genomic Medicine Service approval.Created: 31 Jan 2023, 2:49 p.m. | Last Modified: 31 Jan 2023, 2:49 p.m.
Panel Version: 2.3
Comment on mode of inheritance: Should be updated from 'both monoallelic and biallelic' to just 'monoallelic' as the literature only reports heterozygous (monoallelic) variants associated with EKVP. Rare biallelic forms of EKVP have so far only been reported for GJB3 (OMIM:133200).Created: 5 Apr 2022, 1:19 p.m. | Last Modified: 5 Apr 2022, 1:19 p.m.
