Mid-Ulster has been identified as a "giant hotspot" by scientists studying a gene defect.
This 'giant gene' causes people to grow abnormally tall.
One in 150 people in Mid-Ulster carry the gene.
That's in stark contrast to one in 1,000 in Belfast.
More than three-quarters of people will not develop health issues.
For some it will however cause problems.
Scientists hope their work will identify those at risk of passing on the gene.
A screening programme was held in Mid-Ulster back in 2013.
The gene caused Drummullan-born Charles Byrne to grow around 7ft 6in tall.
Born in 1761 and known as the 'Irish Giant' from Cookstown, his skeleton has been preserved in the Hunterian Museum at Royal College of Surgeons in London.
