Progeria and Genetic Functions

The webinar on Hutchinson Guilford Progeria Syndrome (HGPS) covers its genetic basis, symptoms, and current research. Progeria is a rare genetic disorder causing rapid aging in children due to mutations in the LMNA gene. The video explains DNA basics, gene function, and the impact of the C to T mutation in exon 11, leading to the production of progerin instead of lamin A. This results in cellular instability and premature aging. Current treatments focus on symptom management and new therapies are in clinical trials. The webinar concludes with a quiz to test understanding.
