The rating of this gene has been updated to Red and the mode of inheritance set to 'X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)' following NHS Genomic Medicine Service approval.Created: 1 Feb 2023, 7:44 a.m. | Last Modified: 1 Feb 2023, 7:44 a.m.

Arina Puzriakova (Genomics England Curator)
Comment on list classification: This gene is associated with a syndromic ID phenotype. Gastrointestinal disturbances were exhibited by one patient with severe constipation and a recurrent paralytic ileus (PMID: 32896648), and another patient with persistent gastro-oesophageal reflux (PMID: 30734472) although the latter isn't within the scope of this panel. Based on only one individual found displaying a phenotype that is relevant to this panel, recommending this gene is rated Red until further cases are reported. Cases are more likely to be picked up via other routes such as the ID panel.Created: 21 Dec 2022, 11:56 a.m. | Last Modified: 21 Dec 2022, 11:56 a.m.
