Abstract

About 3-5 percent of papulation suffer from MENTAL RETARDATION (MR) mildly to severely. One of the most common causes of MR is chromosmal aberrations.In this research, Chromosomal study was performed for 100 Mental Retarders (MRs) by G-banding Method.100 MRs were 66 boys and 34 girls, 31 cases (percent) of MRs had chromosmal aberration.23 MRs were suffering from down's syndrome: 21 cases with 21 free Trisomy, 1 case chrmosomal mosaism and residual case had Robertsonian traslocation 14:21 also chromosomal mosaism. Other 8 MRs had be structural berrations in chromosomes such as inversion (3 cases), partial trisomy (1 case), ring 22 chromosome (1 case) and breakages in different chromosomes (3 cases). The results showed that chromosome aberrations are frequent between Mental Retarderes and the most common chromosomal aberrations occur between MRs is 21 free trisomy.
