Definitions related to bardet-biedl syndrome:
-
A collection of autosomal recessive syndromes with similar phenotypes associated with mutations in at least one BBS gene. Clinical characteristics of this genetically heterogenous syndrome may include, but are not limited to, obesity, diabetes, hand anomalies, retinal dystrophy, genital anomalies, developmental delay, hypertension, and hypercholesterolemia.NICHD Pediatric TerminologyU.S. National Cancer Institute, 2021
-
An autosomal recessive disorder characterized by RETINITIS PIGMENTOSA; POLYDACTYLY; OBESITY; MENTAL RETARDATION; hypogenitalism; renal dysplasia; and short stature. This syndrome has been distinguished as a separate entity from LAURENCE-MOON SYNDROME. (From J Med Genet 1997 Feb;34(2):92-8)NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
An autosomal recessive inherited syndrome caused by mutations in at least fourteen different genes, called BBS genes. It is characterized by loss of vision, obesity, diabetes, hypertension, hypercholesterolemia, polydactyly, intellectual disability, genital organs abnormalities, and delayed development of motor skills.NCI ThesaurusU.S. National Cancer Institute, 2021

Bardet-Biedl syndrome is a disorder that affects many parts of the body. The signs and symptoms of this condition vary among affected individuals, even among members of the same family. Vision loss is one of the major features of Bardet-Biedl syndrome. Loss of vision occurs as the light-sensing tissue at the back of the eye (the retina) gradually deteriorates. Problems with night vision become apparent by mid-childhood, followed by blind spots that develop in the side (peripheral) vision. Over time, these blind spots enlarge and merge to produce tunnel vision. Most people with Bardet-Biedl syndrome also develop blurred central vision (poor visual acuity) and become legally blind by adolescence or early adulthood. Obesity is another characteristic feature of Bardet-Biedl syndrome. Abnormal weight gain typically begins in early childhood and continues to be an issue throughout life. Complications of obesity can include type 2 diabetes, high blood pressure (hypertension), and abnormally high cholesterol levels (hypercholesterolemia). Other major signs and symptoms of Bardet-Biedl syndrome include the presence of extra fingers or toes (polydactyly), intellectual disability or learning problems, and abnormalities of the genitalia. Most affected males produce reduced amounts of sex hormones (hypogonadism), and they are usually unable to father biological children (infertile). Many people with Bardet-Biedl syndrome also have kidney abnormalities, which can be serious or...MedlinePlus GeneticsU.S. National Library of Medicine, 2021

Bardet-Biedl syndrome (BBS) is an inherited condition that affects many parts of the body. People with this syndrome have progressive visual impairment due to cone-rod dystrophy; extra fingers or toes (polydactyly); truncal obesity; decreased function of the male gonads (hypogonadism); kidney abnormalities; and learning difficulties....National Center for Advancing Translational Sciences
