Study Population

The pathogenesis of MTS is largely unknown and whilst the condition is known to be more prevalent in females, familial risk factors are largely unknown. To our knowledge, no studies have previously assessed the prevalence of MTS in relatives of those with the condition.

You may qualify if:
