FG Onco Tamoxifen
Pharmacogenetics of tamoxifen treatment
Tamoxifen is the most selective modulator used in the treatment of breast cancer. One of the main causes of the difference in the interindividual response to tamoxifen is the presence of alleles in the CYP2D6 gene associated with a null, decreased or increased enzyme activity compared to normal. The CYP2D6 gene codes for the enzyme CYP2D6, which converts tamoxifen to endoxifene, its active metabolite and the main responsible for its antineoplastic activity. As a consequence, a decrease in CYP2D6 enzyme activity results in a lower efficacy of tamoxifen treatment.
The Genetic Profile FG – Onco Tamoxifen studies the 11 major allelic variants of the CYP2D6 gene with known clinical relevance. These 11 allelic variants provide coverage greater than 97% of all alleles described in this gene. The aim of the analysis is to identify those patients with an increased likelihood of less effective tamoxifen treatment and prone to develop serious side effects.
