Hutchinson-Gilford Progeria Syndrome (HGPS)
Hutchinson-Gilford progeria syndrome (HGPS) is an incredibly rare genetic disorder that fast-forwards the aging process, beginning in early childhood. At our company, we have dedicated ourselves to the paramount endeavor of diagnosing and treating rare diseases and designing innovative research programs to develop potential therapies.
Overview of HGPS
HGPS, a genetic disorder, affects only 1 in 4 to 8 million live births. Beyond the limitations of its occurrence, the disease characteristically accelerates aging during a child's first years of life. Its symptoms include growth failure, loss of body fat and hair, aging skin, stiffness of joints, hip dislocation, generalized atherosclerosis, cardiovascular disease, and stroke.

Pathogenesis of HGPS
The pathogenesis of HGPS is the mutations in the LMNA gene coding for lamin A and lamin C, proteins integral to the nuclear envelope's structure. The most common mutation is a single-base substitution at coding position 608 of the LMNA gene, which creates a mutant protein named progerin. Progerin lacks a processing site necessary for lamin A's final maturation, consequently provoking structural changes in the nuclear envelope. This gathered progerin interrupts cell processes such as DNA repair, transcription, and cell proliferation, driving the premature aging cellular phenomenon symptomatic of progeria.

Diagnostics Development of HGPS
Typical diagnosis around a mesh of medical history, physical examination, and precise diagnostic tests. Genetic testing has proven the most definitive, in detecting LMNA gene mutation. Moreover, therapeutic efficiency can be evaluated using key markers during the research phase.
Therapeutics of HGPS
Small Molecule Drugs Therapy
Drugs such as MG132, JH4, farnesyltransferase inhibitor (lonafarnib), remodelin, and the mTOR inhibitor (rapamycin) reduce progerin synthesis and toxicity, managing HGPS symptoms.
Gene Therapy
Gene therapy's design is to hinder progerin accumulation, such as CRISPR/Cas9-mediated reduction of lamin A/progerin, thereby improving HGPS mice's health and lifespan.
