Understanding the Link Between Bardet-Biedl Syndrome and Laurence Moon


April 10, 2024

Exploring the Connection Between Two Rare Conditions

Have you ever heard of Bardet-Biedl syndrome or Laurence Moon syndrome? These are two very rare health conditions that can affect people in similar ways. Sometimes, these two conditions are so much alike that people get them mixed up. Let’s take a closer look at how they are connected.

What is Bardet-Biedl Syndrome?

Bardet-Biedl syndrome, also called BBS, is a rare condition that can cause problems with sight, extra fingers or toes, hard-to-control hunger and weight gain, and kidney issues. Kids with BBS might also find learning to be a bit harder. Doctors can tell someone has BBS by looking for these signs and doing special tests called genetic tests to look at a person’s genes, which are like the body’s instruction book.

What is Laurence Moon Syndrome?

Laurence Moon syndrome is another rare condition. It shares a few signs with BBS, like problems with sight and learning. But it also has its own signs, like trouble with moving legs that can get stiff or hard to control.

Why Do People Confuse Them?

In the past, when doctors saw someone with these signs, they sometimes thought it was just one big condition called “Bardet-Biedl Laurence-Moon syndrome.” But now we know they are separate. Even though they are different, they can look a lot alike because they both can affect the same parts of the body.

The Big Differences

So, how can doctors tell them apart? They use genetic testing to look for variants (or changes) in certain genes. Depending on the test results, they can figure out if it’s BBS or Laurence Moon.

Why It’s Important to Know:

Knowing the difference between BBS and Laurence Moon can help doctors take better care of someone with these conditions. Obesity is a significant aspect of Bardet-Biedl syndrome, impacting the health and well-being of individuals affected by this genetic disease. Understanding the link between Bardet-Biedl syndrome and obesity, and how they differ from Laurence Moon syndrome allows healthcare providers and families to choose the best treatments and give advice on what to expect in the future.

You are not alone. A community and a treatment for obesity in individuals living with BBS are out there – find out more today.

The majority of individuals living with BBS experience intense, hard-to-control hunger contributing to obesity. There is an approved treatment that significantly reduced measures of weight and hunger in clinical trials in people living with BBS. Take the questionnaire to connect to educational resources.
