Healthy volunteers help unlock genetic secrets of heart disease
NCT ID NCT04931498
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how two specific genes, SWAP70 and GMPR, may influence the risk of heart disease. Researchers will analyze blood samples and health data from 100 healthy volunteers who are part of a larger research resource. The goal is to better understand the biological mechanisms behind these genetic factors, which could eventually lead to new treatments or prevention strategies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could improve understanding of how certain genes influence heart disease risk and point toward new drug targets.
- What could go wrong
- This is an observational study with only 100 healthy volunteers, so findings may not apply to the general population or lead directly to treatments.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study will only recruit healthy volunteers who have previously consented to being contacted for future studies by the NIHR Cambridge BioResource, which is a panel of around 20,000 volunteers, both with and without health conditions, who are willing to be approached to participate in research studies investigating the links between genes, the environment, health and disease. Volunteers who join the NIHR BioResource have donated their DNA via a blood or saliva sample that is used together with other information, such as sex and ethnicity, to match them to specific research studies. Participants for this study are identified by having the appropriate genetic sequence in one of the two genetic loci we are investigating (SWAP70, GMPR).

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Have consented to be part of the NIHR BioResource; * Are aged 18 years and above; * Have given written informed consent to participate in the GENBIO study; * Are carriers or non-carriers of the candidate functional genetic variant(s) of interest. Exclusion Criteria: Have a chronic disease, including cardiovascular diseases, autoimmune diseases and cancer. Additional exclusion criteria to be applied at the discretion/opinion of the CI/collaborator, based on the population of available volunteers for recall and the genetic variant of interest (e.g. allele frequency): * Have a biological first-degree relatives (parents, brothers, sisters or children) who are suffering or have suffered from a disease/condition in the opinion of the CI/collaborator that, from a genetic standpoint, may affect the study validity; * Are current regular smokers. Regular ex-smokers are suitable if they stopped smoking \>10 years ago (regular defined as 1 pack year in both instances); * Have ≥3 alcoholic drinks per day; * Have a diagnosis of hypertension, or history of consistently high blood pressure readings, e.g. \>140/90 mmHg; * Have a diagnosis of hypercholesterolemia, or history of consistently high cholesterol levels, e.g. total cholesterol level \>6 mmol/l; * Are obese (i.e. BMI \>30); * Are unwilling to fast and not to consume products containing alcohol or caffeine 12 hours prior to procedures.
