Eleanor Williams (Genomics England Curator)

Comment on list classification: MDH2 association with Epileptic encephalopathy, early infantile, 51 reported in 3 unrelated cases (PMID: 27989324). Psychomotor delay appears to be from early on and not progressive.

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.
