Kleine-Levin syndrome
Gene: CRY1
Comment on list classification: Adding this gene as red to the panel after consultation with the Genomics England clinical team. There are sufficient cases to rate higher, but the phenotype, although sleep related, is not relevant to the panel scope which targets hypersomnolence, so keeping red for now.Created: 7 Oct 2020, 3:03 p.m. | Last Modified: 7 Oct 2020, 3:03 p.m.
