The observation that schizophrenia is associated with duplications of a certain copy number variant (CNV),while autism spectrum disorders are associated with deletions of the same CNV,suggests that _____.
A) CNV mutations are present in all psychiatric disorders
B) both disorders have identical phenotypes
C) both disorders have an environmental component
D) both disorders share common developmental pathways
E) neither disorder has a genetic component

The observation that schizophrenia is associated with duplications of a certain copy number variant (CNV),while autism spectrum disorders are associated with deletions of the same CNV,suggests that _____.
A) CNV mutations are present in all psychiatric disorders
B) both disorders have identical phenotypes
C) both disorders have an environmental component
D) both disorders share common developmental pathways 
E) neither disorder has a genetic component

Quizplus · Accepted Answer

The observation suggests that both schizophrenia and autism spectrum disorders share common developmental pathways, as they are associated with different variations of the same CNV. This implies that both disorders may have similar underlying genetic mechanisms and may be related to each other in some way. This does not necessarily mean that CNV mutations are present in all psychiatric disorders, that both disorders have identical phenotypes, or that both disorders have an environmental component. It also does not suggest that neither disorder has a genetic component.
