Report of a four-year-old boy with Progeria without total Alopecia
Hutchinson-Gilford progeria syndrome is an extremely rare condition with features of premature and accelerated aging. The pattern of inheritance is unclear, although autosomal dominant mutations have been proposed. The disease presentation is usually in infancy and early childhood with a characteristic phenotype of short stature, abnormal skin and nail, beaked nose, loss of subcutaneous f...
متن کاملModel of human aging: Recent findings on Werner’s and Hutchinson-Gilford progeria syndromes
The molecular mechanisms involved in human aging are complicated. Two progeria syndromes, Werner's syndrome (WS) and Hutchinson-Gilford progeria syndrome (HGPS), characterized by clinical features mimicking physiological aging at an early age, provide insights into the mechanisms of natural aging. Based on recent findings on WS and HGPS, we suggest a model of human aging. Human aging can be tri...
متن کاملA Case Report of Hutchinson-Gilford Progeria Syndrome
Hutchinson-Gilford Progeria Syndrome (HGPS), a rare genetic condition occurs one in every 8 million live births. HGPS is characterized by premature aging in various organs. The average survival rate of the affected patients is 13 years, and their most common causes of death are myocardial infarction and stroke. This disease occurs due to a gene mutation in the chromosomes of the patient. There ...
متن کاملVitamin D receptor signaling improves Hutchinson-Gilford progeria syndrome cellular phenotypes
Hutchinson-Gilford Progeria Syndrome (HGPS) is a devastating incurable premature aging disease caused by accumulation of progerin, a toxic lamin A mutant protein. HGPS patient-derived cells exhibit nuclear morphological abnormalities, altered signaling pathways, genomic instability, and premature senescence. Here we uncover new molecular mechanisms contributing to cellular decline in progeria. ...
متن کاملProgeria Syndrome Mechanisms of Premature Vascular Aging in Children With Hutchinson-Gilford Progeria Syndrome
Hutchinson-Gilford progeria syndrome is a rare, segmental premature aging syndrome of accelerated atherosclerosis and early death from myocardial infarction or stroke. This study sought to establish comprehensive characterization of the fatal vasculopathy in Hutchinson-Gilford progeria syndrome and its relevance to normal aging. We performed cardiovascular assessments at a single clinical site ...
