Abstract

Abstract The gray matter volumes of 58 pairs of twins ranging in age from 12 to 18 were measured by MRI to explore the genetic and environmental impacts on gray matter volume in twin children and adolescents. By means of A/C/E structural equation modeling, it was found that the gray matter volume in children and adolescents was jointly affected by genetic (A: 0.89) and environmental factors while genetic factors play a greater role. The gray matter volume in frontal lobe, parietal lobe, occipital lobe and lateral temporal lobe was mainly affected by genetics (A: 0.7–0.89), where as the gray matter volume in medial temporal lobe and cingulate cortex was affected by both genetics and environment.

Abstract

To explore the effects of the genetic and environmental factors on intelligence of children and adolescent from the Southwest China Prospective Twin Registry (SCPT).The intelligence was investigated by using the Wechsler Intelligence Scale for Children (C-WISC) in 333 twin pairs aged 6-16 years. The effects of genetic and environmental factors on IQ were analyzed by using structural equation modeling (SEM) and correlation analysis method. The effects in different sex and age groups in this population were also investigated.Genetic influence accounted for 0.43 of total IQ variance and 0.37 of verbal IQ in 6-16 years old children and adolescent, but there was no significant genetic effect on performance IQ. The heritability of children aged 10-16 years was higher than that of those aged 6-10 years (total IQ: 0.82 vs 0.00, verbal IQ: 0.80 vs 0.00, performance IQ:0.51 vs 0.00). In males the heritability of verbal IQ (0.47) was higher than that in females (0.05). The shared environmental influences accounted fo r the majority of variance of performance IQ in both males and females.There is moderate heritability on the total IQ and verbal IQ, while shared environmental factors played important roles on the variance of performance IQ. The heritability of IQ, verbal IQ and performance IQ are higher in older children and adolescent than that in younger children.
