Genetics molecular testing

These data emphasize the complex nature of the molecular mechanisms controlling polymorphic DPD activity in vivo. The clinical utility for genetic polymorphism testing to date is not optimal because of its low sensitivity and unknown specificity (28). Overall, it can be remarked that the splice site mutation IVS14+1G>A causes severe, even lethal, 5-FU-related toxicity. Unfortunately, the roles of other polymorphisms in the DPYD gene in the severe 5-FU-related toxicity are not clarified.

Molecular testing facilitates identification of genetic disease but carries risk for identification of uninterpretable and unsought information. 

The DAP polyamide dendrons conjugated to PNA-peptide chimera and decorated with Gd(III) complexes of D03A ligand were tested as plausible candidates for genetic molecular imaging using MR modality (Scheme 15.32). The Tj relaxivity was increased with the dendron generation.

The three-dimensional strucmres of Cro and of the lambda repressor protein have been determined by x-ray crystallography, and models for their binding and effecting the above-described molecular and genetic events have been proposed and tested. Both bind to DNA using hehx-turn-helix DNA binding domain motifs (see below).
