Core Tip

Core Tip: This study presents a rare case of a ten-year-old boy with Duchenne muscular dystrophy (DMD) coexisting with autism spectrum disorder and epilepsy. By investigating the differential expression of miRNAs, we identified a significant downregulation of miR-132-3p in the DMD patient compared to the comorbid DMD case. This suggests that miR-132-3p downregulation may have contributed to accelerated muscle atrophy through failed silencing of the phosphatase and tensin homolog-mediated apoptotic pathway. Our findings emphasize the importance of studying such rare DMD comorbidities to enhance understanding of disease heterogeneity and improve diagnosis and treatment strategies.
