Investigation of microdeletions in syndromic intellectual disability by MLPA in Iranian population.

Abstract

Intellectual Disabilities (ID), defined as a state of developmental deficit, result in significant limitation of intellect and poor adaptation behavior. A number of genetic factors can result in ID, such as chromosomal abnormalities, copy number variation, and single gene defect. Karyotyping is the routine method for detecting chromosomal abnormalities in patients with ID. More recently, the Multiplex Ligation-dependent Probe Amplification (MLPA) method has been applied for detecting microdeletion/duplication in patients with dysmorphism and ID.
