Hutchinson–Gilford progeria syndrome is a rare genetic disorder caused by LMNA mutations that generate progerin, a toxic protein disrupting nuclear structure and accelerating ageing. Children develop rapid cardiovascular decline, growth failure and systemic tissue deterioration, making HGPS one of the most important models for understanding human ageing.

Dyskeratosis congenita is a rare inherited telomere‑maintenance disorder caused by mutations in DKC1, TERT, TERC and POT1. Accelerated telomere shortening leads to premature cellular ageing, bone‑marrow failure, mucocutaneous abnormalities and multisystem disease. The condition provides key insight into how telomere biology shapes human ageing and tissue regeneration.

A laminopathy is a disorder caused by mutations in genes encoding nuclear‑lamina proteins, most notably LMNA, which produces lamin A…

Premature ageing describes the accelerated decline of cellular and physiological functions caused by genomic instability, telomere attrition, mitochondrial dysfunction and chronic inflammation. These processes activate ageing pathways earlier than expected, leading to early onset of tissue deterioration, reduced homeostasis and increased vulnerability to age‑related diseases.

Ageing is a gradual biological process driven by genomic instability, telomere shortening, mitochondrial dysfunction and cellular senescence. These changes reduce physiological resilience, impair tissue repair and increase susceptibility to chronic disease. Understanding the mechanisms of ageing provides insight into longevity, healthspan and the development of age‑related disorders.
