Among the gene families implicated in neurodevelopmental disorders, voltage-gated calcium channel genes—including CACNA1A (encoding Cav2.1), CACNA1C (Cav1.2), and CACNA1H (Cav3.2)—are of particular interest due to their central roles in neuronal signaling, excitability, and neurodevelopment [3]. The gene discussed is CACNA1C; the disease is neurodevelopmental disorder.
