Abstract
Objective. To detect subtelomeric copy number variations (deletions and duplications) using Multiplex Ligation-Dependent
Probe Amplification (MLPA) technique in children with idiopathic mental retardation.
Methods. All children presenting to the genetics out-patient department for evaluation of mental retardation or
developmental delay over a period of two years, for whom no identifiable cause could be found by clinical evaluation,
karyotyping, neuroimaging and other relevant investigations.
Results. In the present study, two cases deletions and one case of duplication were detected amongst 65 cases with
idiopathic mental retardation/ global developmental delay. The overall detection rate is 4.6%. The detection rate is higher
(13%) in children with facial dysmorphism.
Conclusion. MLPA for subtelomeric regions is recommended for evaluation of children with idiopathic mental retardation/
global developmental delay were included in the study.
