Rebecca Foulger (Genomics England curator)

Comment on mode of inheritance: Monoallelic (AD) mode of inheritance supported by OMIM and DD-G2P.
Created: 3 Oct 2017, 11:34 a.m.
Comment on list classification: Updated rating from Amber to Green based on new OMIM gene/disease relationship for MIM:617506.
In 4 unrelated patients with Noonan syndrome-like disorder with loose anagen hair-2 (NSLH2; 617506), Gripp et al. (2016) identified heterozygosity for de novo missense mutations in the PPP1CB gene. All had developmental delay. Plus confirmed DD-G2P gene for 'Rasopathy with developmental delay, short stature and sparse slow-growing hair'.

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.
