Bardet-Biedl syndrome 1 is primarily caused by changes in the BBS1 gene, which provides instructions for making a protein involved in the function of cilia, small hair-like structures on the surface of cells. These genetic changes disrupt the normal function of cilia, leading to the various symptoms associated with the syndrome. The condition is inherited in an autosomal recessive pattern, meaning that an individual must receive a faulty gene from both parents to be affected. Risk factors include having parents who are carriers of the mutated gene, particularly in populations where such genetic changes are more common. Genetic counseling can help assess the risk of passing the condition to offspring.

Genetische Risikofaktoren

Bardet-Biedl syndrome 1 is primarily caused by genetic mutations that affect the function of cilia, which are small hair-like structures on cells. These mutations disrupt the normal signaling pathways and cellular processes, leading to the symptoms associated with the syndrome. The genetic basis of Bardet-Biedl syndrome 1 involves several specific genes that, when mutated, increase the risk of developing the condition.

• BBS1 gene mutation: Mutations in the BBS1 gene are one of the most common causes of Bardet-Biedl syndrome 1. This gene provides instructions for making a protein that is involved in the structure and function of cilia. When the BBS1 gene is mutated, it can lead to the malfunction of cilia, contributing to the development of the syndrome.

• BBS2 gene mutation: The BBS2 gene is another gene associated with Bardet-Biedl syndrome 1. Mutations in this gene can disrupt the normal function of cilia, similar to mutations in the BBS1 gene. This disruption can lead to the various symptoms observed in individuals with the syndrome.

• BBS4 gene mutation: Mutations in the BBS4 gene also contribute to the risk of Bardet-Biedl syndrome 1. The BBS4 gene is important for the proper functioning of cilia. When mutated, it can impair cilia function, leading to the characteristic features of the syndrome.

• BBS10 gene mutation: The BBS10 gene is another genetic factor involved in Bardet-Biedl syndrome 1. Mutations in this gene can lead to defective cilia, which are crucial for cellular signaling and function. This defect can result in the clinical manifestations of the syndrome.

Bardet-Biedl syndrome 1 was first identified in the late 19th and early 20th centuries through the work of Georges Bardet and Arthur Biedl, who independently described families with a combination of symptoms that were later recognized as a single genetic disorder. The syndrome is characterized by a variety of features, including vision problems, obesity, extra fingers or toes, and kidney abnormalities. It was initially observed in small, isolated populations, which helped researchers identify its genetic basis.

The discovery of Bardet-Biedl syndrome 1 was not linked to major outbreaks, as it is a rare genetic condition rather than an infectious disease. Its impact on mankind is significant for affected individuals and their families, as it can lead to lifelong challenges and health complications. The syndrome has provided valuable insights into the role of genes in human development and the functioning of various body systems.

Research into the genetic causes of Bardet-Biedl syndrome 1 advanced significantly in the late 20th century with the advent of molecular genetics.
