Hutchinson–Gilford Progeria Syndrome (HGPS), or progeria, is an exceedingly rare genetic disorder marked by accelerated aging. Affected individuals usually die prematurely around 14-15 years old, mainly due to cardiovascular complications. Caused by a spontaneous autosomal dominant point mutation in the LMNA gene encoding the lamin A and C proteins, this mutation generates an abnormally spliced lamin A protein, progerin. Progerin accumulates beneath the nuclear lamina and activates downstream effectors, disrupting cellular morphology and physiology. This results in a systemic disorder that mainly impacts the cardiovascular system, bones, skin, and overall growth.
