BBS5

BBS5 is a gene that encodes a protein involved in the Bardet-Biedl syndrome (BBS), a rare genetic disorder characterized by a variety of symptoms affecting multiple organ systems. The BBS5 protein is part of a complex of proteins known as the BBSome, which plays a crucial role in the function of cilia, hair-like structures found on the surface of many cells.

Function

The BBS5 protein is a component of the BBSome, a protein complex that is involved in the transport of proteins within cilia. Cilia are important for various cellular processes, including cell signaling and sensory perception. Mutations in the BBS5 gene can disrupt the function of the BBSome, leading to ciliary dysfunction and contributing to the development of Bardet-Biedl syndrome.

Clinical Significance

Mutations in the BBS5 gene are associated with Bardet-Biedl syndrome, a rare genetic disorder characterized by obesity, retinal degeneration, kidney abnormalities, and other symptoms. Individuals with Bardet-Biedl syndrome may also experience intellectual disability, polydactyly (extra fingers or toes), and other health issues. The severity and specific features of the syndrome can vary widely among affected individuals.

Research

Research on BBS5 and other genes associated with Bardet-Biedl syndrome is ongoing, with the goal of better understanding the molecular mechanisms underlying the disorder and developing potential treatments. Studies investigating the function of the BBSome and its role in ciliary biology are helping to shed light on the pathogenesis of Bardet-Biedl syndrome and related ciliopathies.
