I don't know

PMID: 30184290 reports on 2 individuals, both harboring the same de novo missense variant in CAMK2G [p.(Arg292Pro)]. One of these subjects was previously reported by the same group (PMID: 23033978). The authors provide clinical details on both individuals who presented with hypotonia and severe intellectual disability and additional features (the latter rather specific to each patient). The study focuses on the functional impact of this variant, demonstrating a gain-of-function effect (through increased phosphotransferase activity) and providing evidence for involvement of CAMK2G in neuronal maturation and neurodevelopment.

This gene has been included in ID/ASD panels offered by different diagnostic labs.

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.
