Muscle Mystery: Orkney Genes Linked to Superhuman Physique

Stuart Flett, 60, from Cumbria, has a lifetime history of unusual muscle development and debilitating spasms. Researchers investigating the Viking Genes project now believe his family's Orkney roots may be linked to a rare genetic condition known as neuromyotonia. This condition is suspected to bestow an exceptionally strong physique while also causing involuntary muscle contractions and prolonged tension.

The Flett family's connection to Orkney, specifically the island of Flotta, is a focal point for the study. Stuart's father was born there, making him 50% Orcadian. He first noticed his distinctive symptoms in childhood, which progressed into adulthood, often leading to him being wrongly accused of steroid use due to his naturally muscular build.

Neuromyotonia symptoms include muscles that are slow to relax and severe, whole-body spasms when triggered. Stuart's daughter, Dr. Chloe Flett, also diagnosed with the condition, is involved in the research aimed at understanding its genetic basis. The discovery of the responsible gene could pave the way for gene therapies to combat muscle wasting diseases.

Professor Jim Flett Wilson, leading the Viking Genes study, described the condition as exceptionally rare, possibly unique to Stuart's family. The research involves comparing DNA from Orkney volunteers and Stuart's extended family to identify the causative gene, a process currently in its initial stages.
