A large international study led by FIMM researchers has identified genetic factors that influence how people tolerate common blood pressure medications.
The study highlights how genetic variants enriched in the Finnish population can reveal biological insights that may remain hidden in larger but more genetically diverse populations.
One of the study’s most striking findings was a genetic variant in a gene called NTSR1 that protects against the persistent dry cough often caused by ACE inhibitors, a widely used type of blood pressure medication. The variant is found in around 3% of Finns but is extremely rare in most other populations.
The researchers also linked the CYP3A4*22 variant, which affects a key drug-metabolizing enzyme, to an increased likelihood of switching away from calcium channel blockers.
According to the lead authors Felix Vaura and Samuli Ripatti, the findings move the field a step closer to more personalized treatment of hypertension, where medication choices could be guided by a patient's genetic profile.
The study was published in the European Heart Journal (link in the comments).
A gene variant found in 1 in 30 Finns may protect against the dry cough that often leads patients to stop taking ACE inhibitors, a common blood pressure medication. The study also identified a genetic predictor of intolerance to another blood pressure drug class, bringing personalized hypertension t...
