Which of the examples of genetic testing below are prognostic tests? Which are diagnostic? (a) Individual sequencing (personal genomics) identifies a mutation associated with Alzheimer’s disease. (b) ASO testing determines that an individual is a carrier for the mutant b@globin allele (bS) found in sickle-cell anemia. (c) DNA sequencing of a breast tumor reveals mutations in the BRCA1 gene. (d) Genetic testing in a healthy teenager identifies an SNP correlated with autism. (e) An adult diagnosed with Asperger syndrome (AS) has a genetic test that reveals a SNP in the GABRB3 gene that is significantly more common in people with AS than the general population.
