University of Calgary researchers have created a new tool to analyze genetic mutations that they say is quicker and more cost-effective than traditional methods.
One-pot DTECT is a novel detection methodology formulated with off-the-shelf reagents that streamlines the capture of genetic signatures of interest by combining multiple enzymatic activities into an efficient one-pot reaction.
The genetic data can be analyzed in three ways: quantitatively, qualitatively and visually.

“One-pot DTECT can confirm the presence of variants and determine the frequency of these mutations precisely,” explains Pierre Billon, senior author on the paper published in Cell Reports Methods. “Accurate detection of genomic sequences and their mutations is critical for various application in research and clinical settings.”
The researchers also demonstrated the tool's accuracy in clinical settings, particularly in diagnosing blood disorders like sickle cell anemia. The results showed 100% accuracy in identifying genetic signatures with no false positives or negatives. Moreover, One-pot DTECT can be used on small DNA samples, such as bloodspots, making it valuable for diagnosing newborns and toddlers.
The tool's potential applications extend to a wide range of genetic mutations for various disorders, including cystic fibrosis.
