Adult onset neurodegenerative disorder
Gene: XK
The rating of this gene has been updated to Green 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, 12:22 p.m. | Last Modified: 1 Feb 2023, 12:22 p.m.

Comment on list classification: There is enough evidence for this gene to be rated Green at the next major review. Neurodegenerative component resembling Huntington disease becomes apparent in older individuals.Created: 23 Aug 2022, 9:41 a.m. | Last Modified: 23 Aug 2022, 9:41 a.m.

Associated with relevant phenotype in OMIM, but not associated with phenotype in Gen2Phen. Numerous variants have been reported in cases of McLeod syndrome with or without chronic granulomatous disease (OMIM:300842), including at least two cases in females; severe symptoms were apparent in the index case (11.1) who had marked skewed X-inactivation favouring the wild type allele (PMID: 8619554).Created: 11 Aug 2022, 9:43 a.m. | Last Modified: 11 Aug 2022, 9:43 a.m.
