X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)

Rebecca Foulger (Genomics England curator)

Comment on list classification: Updated rating from Red to Green based on two 2017 papers (a family reported in PMID:28302723, and two unrelated boys in PMID:28584052) supporting causation for MIM:300997.
Created: 4 Sep 2017, 3:02 p.m.
A L254F substitution in OGT was reported by Niranjan et al. 2015 (PMID:25679214) in members of a family with X-linked intellectual disability (XLID). The same variant was reported in 3 affected males from a family by Vaidyanathan et al. (PMID:28302723, 2017).
Created: 4 Sep 2017, 2:58 p.m.
Willems et al, 2017 (PMID:28584052) report two hemizygous mutations in OGT in individuals with X-linked intellectual disability (XLID) and dysmorphic features: R284P and a splicing variant c.463-6T-G, NM_181672.2. Both variants residue in the region of OGT essential for substrate recognition.

Panel promoted to version 2.0

Ellen McDonagh (Genomics England Curator)

12.03.2018: Due to major updates completed (Phase 1, 2 and 3), this panel was promoted to Version 2 in order to reflect the major updates since November 2017 which have resulted in reviews for 836 genes added by Genomics England Curators and the Clinical Team, 130 new Green genes added to the interpretation pipeline (from 751 to 881 Green genes), and the gene total has increased from 1879 to 1927.
