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). This evidence concerns the gene DYNC1H1 and dyneinopathy.
