Premature aging disorders: A clinical and genetic compendium

Area of Science:

• Genetics
• Molecular Biology
• Pediatrics

Background:

• Progeroid disorders are rare hereditary diseases presenting with premature aging phenotypes.
• Hutchinson-Gilford progeria syndrome is well-studied, but a spectrum of other progeroid disorders exists with diverse clinical and molecular characteristics.
• Accurate molecular diagnosis is increasingly feasible with next-generation sequencing (NGS).

Purpose of the Study:

• To provide a comprehensive overview of clinical features and molecular genetics of various progeroid disorders.
• To highlight recent advancements and potential therapeutic strategies for these rare conditions.
• To emphasize the importance of clinical knowledge for patient management and variant interpretation in NGS data.

Main Methods:

• Literature review of well-established and newly identified progeroid disorders.
• Analysis of clinical presentations and underlying molecular genetic mechanisms.
• Synthesis of current findings on diagnostic approaches and therapeutic prospects.

Main Results:

• Detailed characterization of clinical signs and symptoms across different progeroid disorders.
• Elucidation of the molecular pathogenesis for both common and rare premature aging conditions.
• Identification of emerging therapeutic targets and strategies.

Conclusions:

• A broad clinical understanding is crucial for diagnosing and managing progeroid disorders, especially when interpreting NGS data.
• Recent genetic discoveries are improving diagnostic capabilities for these rare diseases.
• Novel therapeutic avenues are being explored, offering hope for future treatments.
