Summary

This study seeks to discover clinically useful tests to improve the diagnosis of a rare and serious heart muscle disease caused by mutations in a gene called 'Lamin'. Patients born with lamin gene mutations have apparently healthy hearts initially, they begin experiencing symptoms in their twenties or thirties, and by age 45 the majority have undergone a heart transplant, experienced a major cardiac complication, or have died. Sudden heart rhythm abnormalities are a major cause of sudden death so earlier diagnosis can save lives by enabling timely treatment or implantation of specialised pacemakers (defibrillators). In clinical practice, diagnosis of lamin heart disease currently relies on the genetic test. Very little is known about the detailed imaging features of the hearts of patients with lamin heart disease although advanced echocardiography and cardiac MRI now offer the opportunity to study the health of the heart without the need for radiation.

Detailed description

* Research participants will undergo resting 12-lead ECG, 24-hour ambulatory ECG, baseline echocardiography, exercise echocardiography, cardiac MRI scan. * Blood samples will be collected in all participants from both centers for immediate laboratory testing. * Blood and urine samples will be collected in all participants and used for metabolomic, proteomic and lipidomic profiling and for targeted metabolite and enzyme analysis. * Blood samples will be collected in all participants for future gene code analysis (DNA / RNA).

Conditions

• Lamin A/C Gene Mutation
• Dilated Cardiomyopathy, Familial
