Autism and autistic traits onset in childhood but persist into adulthood. Little is known about how genetic and environmental factors influence autism and autistic traits into adulthood. We aimed to determine age effects on the heritability of clinically diagnosed autism and the etiological stability of autistic traits from childhood to adulthood using twin methods.

年龄对自闭症遗传性和自闭症特征病因学稳定性的影响

自闭症和自闭症特征在童年时期开始，但持续到成年期。关于遗传和环境因素如何影响成年后的自闭症和自闭症特征，人们知之甚少。我们的目的是使用孪生方法确定年龄对临床诊断的自闭症遗传性的影响以及从童年到成年自闭症特征的病因学稳定性。
