Bardet-Biedl Syndrome.

Area of Science:

• Genetics
• Molecular Biology
• Ophthalmology

Background:

• Bardet-Biedl syndrome (BBS) is a rare, autosomal recessive genetic disorder.
• Characterized by diverse clinical features including rod-cone dystrophy, polydactyly, obesity, and organ defects.
• Symptoms manifest progressively, often worsening in the first two decades of life.

Purpose of the Study:

• To review the current understanding of Bardet-Biedl syndrome genetics, diagnosis, and management.
• To highlight advancements in diagnostic technologies and potential therapeutic strategies.

Main Methods:

• Review of existing literature on Bardet-Biedl syndrome.
• Discussion of genetic findings related to primary cilia function.
• Analysis of current diagnostic and therapeutic approaches.

Main Results:

• Over 20 BBS genes identified, all linked to primary cilia function.
• Genetic diagnosis is becoming more accessible due to multigene sequencing.
• Mouse models show blindness rescue via topical gene therapy; nutritional compensation may delay symptoms.

Conclusions:

• Genetic testing advancements are rapidly improving BBS diagnosis.
• Clinical management is primarily symptomatic.
• Therapeutic interventions, particularly for BBS-related blindness, show potential but require further development.
