A) copy number variants
B) fragile sites
C) inversions
D) deletions
E) translocations

Accepted Answer

Copy number variants (CNVs) are alterations in the DNA that involve duplications or deletions of large segments of chromosomes. Research has shown that CNVs are associated with a higher risk for autism, Alzheimer disease, Parkinson's disease, and schizophrenia. Fragile sites, inversions, deletions, and translocations are also genetic alterations, but are not specifically linked to these disorders.
