  • A majority of individuals living with BBS display rod-cone dystrophy, which presents as atypical retinitis pigmentosa with early macular involvement 
  • Rod-cone dystrophy is one of the most common features of BBS and often leads to a clinical diagnosis

Understanding some common features of Bardet-Biedl Syndrome

Visual impairment

Majority of individuals living with BBS experience vision impairment at some point in their life. Onset of rod-cone dystrophy presenting as atypical retinitis pigmentosa usually occurs between 5 and 10 years of age.


This is a feeling of intense, hard-to-control hunger and is characterized by a preoccupation with food and excessive food-seeking behavior. The intense, hard-to-control hunger can affect sleep, mood, school or work, recreational activities, and relationships with family and friends. 


Individuals living with BBS may experience severe, early-onset obesity. Rapid weight gain occurs in the first years of life, typically before age 5.

Extra fingers and toes

Many individuals living with BBS are born with extra fingers and/or toes. These extra fingers and/or toes are typically surgically removed during the first years of life.

Kidney problems

Individuals living with BBS may experience kidney problems involving cystic tubular disease and anatomical malformations. Renal disease is often detectable before the age of 10, and in some cases before age 1.

Learning disabilities
