For example, studies of the expression of mutated genes have improved our understanding of the reasons for which only a subgroup of patients suffering from neuromuscular diseases (e.g., the Duchenne and Becker dystrophies linked to the DMD gene, dyneinopathies linked to the DYNC1H1 gene) present cognitive, emotional, and/or behavioral problems (including ASD). The gene discussed is DYNC1H1; the disease is neuromuscular disease.
