Do both parents have to be carriers for Bardet Biedl syndrome?
The children of a BBS affected parent will all be carriers of the affected gene, but will not have the syndrome provided that the other parent does not have any changes in the same gene. If the other parent is a carrier of a change in the same gene, then each child has a 50% chance of having the syndrome.
What is the life expectancy of someone with Bardet Biedl syndrome?
On life-table analysis, 25% of BBS patients had died by 44 years, whereas at that age 98% of unaffected siblings were still alive (P < 0.0001). Bardet-Biedl syndrome has an adverse prognosis, with early onset of blindness, obesity, hypertension, and diabetes mellitus.
What does it mean to be a carrier of Bardet Biedl syndrome?
Bardet-Biedl syndrome (BBS1-related) is known as an autosomal recessive condition. For autosomal recessive conditions, if a person has a variation in one copy of their gene, they are a carrier. This means that they are healthy because they also have a working copy of the gene.
Is there a cure for Bardet Biedl syndrome?
Treatment. There is no cure for Bardet-Biedl syndrome . Treatment generally focuses on the specific signs and symptoms in each individual: While there is no therapy for the progressive vision loss, early evaluation by a specialist can help to provide vision aids and mobility training.
Is Bardet Biedl syndrome fatal?
Many people with Bardet-Biedl syndrome also have kidney abnormalities, which can be serious or life-threatening.
How does Bardet Biedl syndrome cause obesity?
Abstract. Background: Bardet-Biedl syndrome (BBS) is a genetic disorder with obesity as one of the major phenotypic criterion, which is proposed to be of neuroendocrine origin. Therefore, disturbances in appetite-regulating hormones have been considered as causative factors.
Is Bardet-Biedl syndrome fatal?
How does Bardet-Biedl syndrome cause obesity?
What does Bardet-Biedl syndrome affect?
Bardet-Biedl syndrome (BBS) is a genetic condition that impacts multiple body systems. It is classically defined by six features. Patients with BBS can experience problems with obesity, specifically with fat deposition along the abdomen. They often also suffer from intellectual impairments.
What causes Laurence Moon Biedl syndrome?
Laurence-Moon syndrome is caused by changes ( mutations ) in the PNPLA6 gene and is inherited in an autosomal recessive manner. Treatment is based on the signs and symptoms present in each person.
What organelle is affected by Bardet Biedl syndrome?
From the analysis of the mutational burden in patients to the functional characterization of the BBS proteins, this syndrome has become a model for both understanding oligogenic patterns of inheritance and the biology of a particular cellular organelle: the primary cilium.
How common is Laurence moon syndrome?
In previous years, Laurence-Moon-Bardet-Biedl syndrome (LMBBS) was a term used to describe an inherited genetic condition that affected approximately 1 in 100,000 babies born.
Who should I talk to about Bardet-Biedl syndrome?
Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. There is no cure for Bardet-Biedl syndrome. Treatment generally focuses on the specific signs and symptoms in each individual:

What are the signs and symptoms of Bardet Biedl syndrome?
Bardet-Biedl syndrome (BBS) affects many parts of the body. Signs and symptoms can vary among affected individuals, even within the same family. The major features include: Progressive vision loss due to deterioration of the retina.
What causes Bardet-Biedl syndrome (BBS)?
