Objective: To detect subtelomeric copy number variations in children with genetic intellectual disability (ID) using multiplex ligation-dependent probe amplification (MLPA), and to investigate the pathogenesis of genetic ID. Methods: A total of 68 children with ID who had normal Results: of G-banding karyotype analysis were included in the study. Their subtelomeric copy number variations were detected using MLPA P036. Results: Among the 68 children with ID, 7 (10%) showed subtelomeric copy number variations, and all the variations were deletion mutations. Among them, 1 case carried 2 subtelomeric microdeletions, and 1 case carried 4 subtelomeric microdeletions. Conclusions: Subtelomeric copy number variations are important causes of genetic ID. MLPA can be used as an economic and effective method for investigating the pathogenesis of genetic ID.
