Olivia Niblock (Genomics England Curator)

Red List (low evidence)

KCNE1 is in close proximity to the Down Syndrome Critical region (DSCR), which is triplicated in Down Syndrome, one of the features of this is Intellectual Disability. However, this gene is also linked to Brugada syndrome - a cardiac phenotype. None of the papers cited their patients as suffering from cardiac symptoms.

Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown

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.
