In RNA-sequencing experiments we find downregulation of genes encoding for subunits of VOCCs, (Cacna1 and Cacnb genes) and changes of gene codifying for potassium-dependent sodium calcium exchanger (Slc24a4 gene), designated NCKX4 [41] also described in iPSCs differentiated neurons established from fibroblasts of Ataxia Telangiectasia (A-T) patients [42]. The gene discussed is SLC24A4; the disease is Ataxia-telangiectasia.
