Progeria, or Hutchinson-Gilford progeria syndrome (HGPS), is an exceedingly rare, fatal genetic disorder characterized by dramatically accelerated aging in children. Affected individuals typically appear normal at birth but begin showing signs of rapid aging within the first 1–2 years of life—including growth failure, loss of subcutaneous fat, alopecia, scleroderma-like skin changes, joint stiffness, and cardiovascular deterioration. Most children with HGPS die in their early teens, usually from heart attack or stroke caused by progressive atherosclerosis.
While there is currently no cure for progeria, significant therapeutic advances have emerged in recent years. The cornerstone of treatment is lonafarnib, a farnesyltransferase inhibitor approved by the U.S. Food and Drug Administration (FDA) in 2023—the first and only drug specifically indicated for HGPS. Lonafarnib works by blocking the abnormal farnesylation of progerin, a mutant form of lamin A that accumulates in cell nuclei and disrupts nuclear architecture and function. Clinical trials demonstrated that lonafarnib significantly improves weight gain, vascular stiffness, bone structure, and audiological outcomes—and most notably, extends median survival by approximately 2.5 years compared with untreated historical controls.
Emerging therapies under active investigation include combination regimens—such as adding statins and bisphosphonates to lonafarnib—to further inhibit progerin production or enhance its clearance. Additionally, RNA-targeted approaches, including antisense oligonucleotides and CRISPR-based gene editing strategies, are being explored in preclinical models to suppress progerin expression at the transcript level. Though still experimental, these modalities hold promise for more precise, disease-modifying interventions in the future.
Management remains multidisciplinary and supportive: pediatric cardiology, nutrition support, physical and occupational therapy, dental care, and psychosocial services are essential components of comprehensive care. Early diagnosis—often confirmed via genetic testing for the pathogenic LMNA c.1824C>T variant—is critical to timely initiation of therapy and optimization of quality of life.
