Jessica is a likely carrier for both TYR Mutations and BRCA 1.
Jessica may be a carrier of both the TYR or BRCA 1 mutations depending on her parents’ genetic makeup. Jessica is half-likely to be a carrier of both the TYR and BRCA 1 mutations if her parents are homozygous. Genetic testing is required to confirm that Jessica is a carrier of both the TYR and BRCA 1 mutations. For individuals with a family history or genetic disorders such as BRCA 1 (Cox and 2020), genetic testing may be available. A genetic test can be used to identify if a person is a carrier of both TYR and BRCA 1 mutations. If Jessica’s test results show that she is a carrier for both BRCA 1 and TYR mutations, then she should be referred to a genetic counselor for further discussion of her risk factors (Trevino et al., 2020).
