Proposed X-linked cerebral palsy + NDD gene

4 unrelated males with predicted deleterious hemizygous REPS2 variants, 2 PTC, 2 missense. 2 de novo, 2 maternally inherited
Phenotypes: 2 w CP + moderate ID/ASD, 2 w NDD NOS
Variants described:
c.1050_1052delGAA;p.K351del
c.1040T>C; p.I347T
c.962C>G; p.S321C
c.1736delA; p.N579Tfs*17

In vitro assay of above 4 variants suggest reduced REPS2 protein stability
Zebrafish model: REPS2 expressed in neuronal cells, REPS2 knock down have reduced motor activity and abN neuronal morphology
Mouse model hemizygous w one of above variants (not specified): reduced performance in cognitive tasks, abnormal neuronal migration pattern on post mortem examination
Mechanism may relate to dopamine signalling?
