Sequence analysis of CACNA1A gene revealed the presence of the heterozygous variant c.1748G>A, resulting in the p.Arg583Gln missense substitution in the putative protein, already described in association with hemiplegic migraine and ataxia (http://grenada.lumc.nl/LOVD2/FHM/home.php). The gene discussed is CACNA1A; the disease is cerebellar ataxia.
