Lamin A/C encoded by LMNA gene is an important component for the maintenance of the nuclear structure. Mutation in the lamin A/C leads to a group of inherited disorders is known as laminopathies. In the human body, there are several mutations in the LMNA gene have been identified. It can affect diverse organs or tissues or can be systemic, causing different diseases. In this review, we mainly focused on one of the most severe laminopathies, Hutchinson-Gilford progeria syndrome (HGPS). HGPS is an immensely uncommon, deadly, metameric ill-timed laminopathies caused by the abnormal splicing of the LMNA gene and production of an aberrant protein known as progerin. Here, we also presented the currently available data on the molecular mechanism, pathophysiology, available treatment, and future approaches of this deadly disease. Due to the production of progerin an abnormal protein leads to an abnormality in nuclear structure, defects in DNA repair, shortening of telomere, impairment in gene regulation which ultimately results in aging in the early stage of life. Now some treatment options are available for this disease but a proper understanding of the molecular mechanism of this disease will help to develop a more appropriate treatment which makes it an emerging area of research.
