Understanding rare variant contributions to autism: lessons from dystrophin-deficient model.

ABSTRACT: Duchenne and Becker Muscular Dystrophy are dystrophinopathies with a prevalence of 1:5000-6000 males, caused by pathogenic variants in DMD. These conditions are often accompanied by neurodevelopmental disorders (NDDs) like autism (ASD; ~20%) and intellectual disability (ID; ~30%). However, their low penetrance in dystrophinopathies suggests additional contributing factors. In our study, 83 individuals with dystrophinopathies were clinically evaluated and categorized based on ASD (36 individuals), ID risk (12 individuals), or controls (35 individuals). Exome sequencing analysis revealed an enrichment of risk de novo variants (DNVs) in ASD-DMD individuals (adjusted p value = 0.0356), with the number of DNVs correlating with paternal age (p value = 0.0133). Additionally, DMD-ASD individuals s
