As apparent from Fig. 1a,b, the neurons from both, healthy individuals and ChAc patients did express ORAI1 and STIM1. The ORAI1 and STIM1 transcript levels were significantly lower in neurons derived from ChAc patients than in neurons derived from healthy individuals  ﻿(Complete gel picture in Supplementary Figure S1). The gene discussed is STIM1; the disease is Choreoacanthocytosis.
