I don't know

Kessi et al summarise KCNC3 in review article "Intellectual Disability and Potassium Channelopathies: A Systematic Review" PMID: 32655623. Note that in PMID:25756792 reported three cases, of which one presented with severe ID and two with mild ID accompanied with cerebellar ataxia. Two different gain of function variants, one had severe ID (D129N) the other mild ID (V535M). Inconsistency of gene as a role in cognition in mouse models. Ataxia predominant phenotype and Green on relevant panels therefore classify as Amber.
