The human progeroid syndrome Hutchinson-Gilford progeria syndrome (HGPS) is predominantly caused by an autosomal dominant mutation (p.G608G, c.1824C. > T) in exon 11 of LMNA gene, resulting in the exposure of a cryptic splicing site and generation of a truncated mutant lamin A isoform, termed progerin. The gene discussed is LMNA; the disease is progeroid syndrome.
