Only few patients of our cohort present potentially deleterious mutations in the genes analyzed (n=9/110). Interestingly, all potentially deleterious variants identified in tubulins genes (n=3) were in patients with schizencephaly. Considering the small proportion of potentially deleterious variants identified in this cohort it becomes clear that other strategies should be used in other to expedite the identification of potential deleterious variants in MCDs.Disclosure: Dr. Souza has nothing to disclose.
