Fewer than 200 children worldwide are known to have Progeria. The median survival for those treated with lonafarnib is now 18.5 years. This article details the clinical, genetic, and epidemiological data that define this accelerated aging syndrome.
Key Takeaways
- Children with HGPS exhibit profound failure to thrive, with weight at birth normal but dropping to <3rd percentile by age 1.
- Diagnosis of HGPS is confirmed by genetic testing identifying the LMNA c.1824C>T mutation.
- Hutchinson-Gilford Progeria Syndrome (HGPS) has an estimated incidence of 1 in 4 to 8 million live births globally.
- HGPS mutation arises de novo in the majority of cases, primarily in the paternal germline.
- Lonafarnib (a farnesyltransferase inhibitor) increases bone mineral density by 28% in treated HGPS patients.
Progeria is an extremely rare disorder affecting about 1 in 20 million people worldwide.
