Arina Puzriakova (Genomics England Curator)
The 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: MOI should be changed from 'both mono- and biallelic' to 'monoallelic' only at the next GMS panel update.
EKVP3 (MIM: 617525) which manifests in transient erythematous patches is associated with monoallelic variants only. Biallelic variants are not pertinent to this panel.Created: 31 Aug 2021, 2:28 p.m. | Last Modified: 31 Aug 2021, 2:28 p.m.
