|Title:||Mental Deficiency And Clinical Signs Most Frequently Associated With Chromosomal Aberrations [deficiencia Mental A Sinais Clinicos Associados Mais Frequentemente A Aberraqoes Cromossomicas]|
|Author:||De Sena L.L.A.|
|Abstract:||A group of 182 mentally handicapped individuals without severe motor problems, whose IQ varied from more than 20 to 68 in 95.6% of the cases, was clinically studied. Analysis of the data indicates that, among the patients with at least seven clinical signs most frequently associated with chromosomal aberrations, there exists a high proportion of individuals whose mental deficiency was determined by the homozygosis of genes with a recessive effect. Environmental factors most probably had a lesser effect as determinants of mental deficiency among these patients than among those who manifest less than seven clinical signs most frequently associated with chromosomal aberrations.|
