Mean age of demise was C ] – Some patients have an atypical phenotype with a more protracted disease course resulting in death in middle age [UMLS: In a 9-year-old patient with a classic clinical sydnrome of Hutchinson-Gilford progeria, Luengo et al. Khalifa described a consanguineous Libyan family in which 2 males and 1 female in 2 sibships related as cousins had seemingly typical Hutchinson-Gilford progeria.

Cardiovascular studies revealed diminishing vascular function with age, including elevated blood pressure, reduced vascular compliance, decreased ankle-brachial indices, and adventitial thickening.

Fibroblasts from the patient with the LR mutation had a substantially enhanced proportion of nuclei with altered morphology and mislocalized lamins. Fibroblasts from the patient with the LR mutation had a substantially enhanced proportion of nuclei with altered morphology and mislocalized lamins. Mutant mice showed striking arterial changes, including progressive loss of vascular smooth muscle cells in the medial layer, elastic fiber breakage, and proteoglycan and collagen deposition in a pattern very similar to that seen in children with HGPS.
