What Is Bardet-Biedl Syndrome?
Inspired by one family's tireless efforts to help their daughter, Everyday Einstein discusses the complex causes of Bardet-Biedl Syndrome, or BBS. Read on for the chance to be a part of the solution!

As you might guess from their diverse capabilities, the internal workings of primary cilia are extremely complicated. Our current understanding of how they work involves over 600 different proteins working both independently and in groups. As you might imagine, with such a complicated setup, there are several things that can go wrong with primary cilia. The conditions caused by something going wrong with primary cilia are referred to as ciliopathies. They include various kidney and liver diseases, and BBS.
One of the things that makes BBS and other ciliopathic conditions so complicated to research is that so many different genes appear to be involved. The symptoms of BBS in particular appear to be caused by a group of genes called “BBS genes.” Over a dozen different BBS genes have been identified, and their primary role appears to be to encode the proteins, which help form the basal body, or base of the primary cilia.
To make things even more complicated, several other groups of genes have been discovered which help the BBS genes do their job, as well as helping to keep the cilia functioning normally after they are formed.
So two different people could have mutations, or changes in one or more of any of these genes which could lead to BBS. Complicating things further is that not everyone with BBS presents with the same set of conditions. Some people might not have obesity, or have it less than others. Still other people might be born with an extra finger or toe, while others show no symptoms until adulthood.
While some of this variation in symptoms can be explained by genetics, most of the cause is still a mystery. The most likely explanation is epigenetic variations to the genome, which are chemical changes to the genome which can occur independently of the genetic sequence. Some of these changes are inherited from your parents, while others can be affected by your lifestyle or environment. (Learn more details on epigenetics here).
One Registry to Rule Them All
This extreme variation in symptoms, genetics, and epigenetics related to BBS is exactly why the I Love Lucy project is raising money to start a BBS registry. A registry provides a central database of patient information related to a particular condition. By storing all of this information in one place, scientists and doctors can start looking for patterns in the data that will help them unlock the secrets of BBS, hopefully leading them to more effective treatments and therapies.
So now that you know more about Bardet-Biedl Syndrome, if you’d like to help out, head over to The I Love Lucy Project to find out more. If giving money isn’t your thing, you can check out some of the other offers associated with the fundraiser, which allow you to get something cool while still helping out.
Speaking of cool, my new middle-grade science fiction novel, Half Worlder, is now available for sale on Amazon for just $2.99. And, throughout the month of December, half of the proceeds go toward the I Love Lucy project.
