   - A significant number of individuals with BBS experience obesity, which often begins in childhood. This is a hallmark feature of the syndrome and can lead to various health complications.

2. Retinal Degeneration:
   - Many patients develop progressive vision loss due to retinal dystrophy, which can lead to night blindness and eventual loss of peripheral vision. This condition is often diagnosed in early childhood.

3. Polydactyly:
   - Extra fingers or toes (polydactyly) is a common physical anomaly in BBS. This can manifest as either fully formed digits or small, rudimentary ones.

4. Kidney Abnormalities:
   - Renal anomalies, such as renal dysplasia or cystic kidneys, are frequently observed. These can lead to chronic kidney disease in some patients.

5. Hypogonadism:
   - Delayed puberty and reproductive issues are common, particularly in males, who may experience underdeveloped genitalia.

6. Learning Disabilities:
   - Cognitive impairment or learning disabilities can occur, although the severity varies widely among individuals.

7. Other Features:
   - Additional symptoms may include dental anomalies, short stature, and behavioral issues. Some patients may also exhibit features of syndromic obesity, such as increased appetite and reduced energy expenditure.

Patient Characteristics

Genetic Background

Bardet-Biedl Syndrome is primarily caused by mutations in genes involved in ciliary function. The inheritance pattern is typically autosomal recessive, meaning that two copies of the mutated gene (one from each parent) are required for the syndrome to manifest. Genetic testing can confirm the diagnosis by identifying mutations in one of the known BBS-related genes.

Demographics
