Bardet-Biedl syndrome type 10 (BBS10) is a rare genetic disorder characterized by a combination of symptoms affecting multiple systems of the body. It is one of the several types of Bardet-Biedl syndrome (BBS), which is a group of genetic disorders that primarily affect the development and function of cilia.

Some common features of BBS10 include:

1. Obesity: Individuals with BBS10 may have early-onset obesity, usually starting in childhood or adolescence. This obesity is often difficult to manage and may be associated with metabolic abnormalities.

2. Vision problems: BBS10 can cause various vision abnormalities, such as retinal dystrophy, which can lead to progressive vision loss and eventual blindness. Other eye problems, such as strabismus (crossed eyes) and astigmatism, may also occur.

3. Polydactyly: Polydactyly refers to the presence of extra fingers or toes. BBS10 individuals may have extra digits, usually in the form of postaxial polydactyly (extra digits on the outer side of the hands or feet). Syndactyly (fusion of fingers or toes) may also be present.

4. Intellectual disability: Some individuals with BBS10 may have intellectual disability, which can range from mild to severe. Learning difficulties and developmental delays are also common.

5. Kidney abnormalities: BBS10 can affect the structure and function of the kidneys, leading to kidney malformations, such as cystic kidneys or renal dysplasia. These abnormalities may result in kidney dysfunction and can progress to end-stage renal disease (ESRD).

6. Hypogonadism: BBS10 individuals may experience hypogonadism, which refers to underdevelopment or dysfunction of the reproductive organs. This can result in delayed puberty, infertility, and hormonal imbalances.

7. Other features: Additional features that may be present in BBS10 include speech and language delays, behavioral problems (such as autism spectrum disorder), diabetes mellitus, and cardiovascular abnormalities.

BBS10 is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated BBS10 gene (one from each parent) to develop the syndrome. Genetic testing can be done to confirm the diagnosis of BBS10. Treatment options focus on managing the specific symptoms and complications associated with the syndrome, such as obesity management, vision aids, and kidney support. A multidisciplinary approach involving various medical specialists is typically required to provide comprehensive care for individuals with BBS10.
