Deletion Status and Intellectual Impairment in Duchenne Muscular Dystrophy

Abstract: SUMMARY The authors collected Verbal, Performance and Full‐scale IQs for 74 patients in whom complete analysis of the dystrophin gene for deletions and duplications had been performed. There was a significant difference in the mean Full‐scale IQ between patients with deletions at the 5' and 3' ends of the gene, with no patients with 5' deletions having mental retardation. No relationship was established between mental retardation and the presence or absence of deletions or length of deletions, and similar dele… Show more

“…Although our sample size was small, experimental results were in line with the literature. 23 At present, some studies about DMD gene mutations of Chinese patients with DMD or BMD have been published. Juan Yang et al 24 used MLPA to detect the mutations in 1053 Chinese patients with DMD/BMD, 59.35 and 11.21% of which were deletions and duplications, respectively.…”

“…Because 60-70% of patients with DMD and BMD have an intragenic deletion, there have been several genotypephenotype studies, but no consistent correlation between deletion type, site, and extent and IQ has emerged [80][81][82]. A recent comprehensive study evidenced how the clinical heterogeneity of DMD patients, namely severity of muscle and brain dysfunction, impacts genotype-phenotype correlation studies, and showed that each brain dystrophin might contribute to the DMD-associated cognitive impairment [83].…”

“…We, and others, have argued that the cognitive profile represents the brain's role in the disorder and is not primarily due to consequences of the physical disability (Hinton et al, 2000(Hinton et al, , 2001. Indeed, some researchers have found an association with molecular characteristics and severity of cognitive presentation (Bushby et al, 1995;Felisari et al, 2000;Moizard et al, 1998).…”
