The phenotype of these diseases ranges from muscular dystrophy, cardiomyopathy and lipodystrophy to systemic diseases, like the premature aging syndrome Hutchinson Gilford Progeria, affecting many tissues. In addition, numerous lamin binding proteins were identified in recent years that are also linked to laminopathy-type diseases, suggesting that lamin complexes with their associated-proteins have a multitude of different functions, whose impairment by disease causing mutations can affect many different tissues.
While laminopathies are rare diseases, there is increasing evidence that some of the processes affected in laminopathies are also involved in prominent diseases, such as diabetes, heart failures, and age related pathologies. Progeria-causing abnormal forms of lamin A have also been found in the elderly, indicating an exciting link between molecular age-related events and lamin dysfunction. |
