Is bardet Biedl a ciliopathy?
Bardet–Biedl syndrome (BBS) is a rare autosomal recessive ciliopathy characterised by retinal dystrophy, obesity, post-axial polydactyly, renal dysfunction, learning difficulties and hypogonadism. Many associated minor features can be helpful in making a diagnosis and are important in the clinical management of BBS.
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 does Bardet Biedl syndrome affect the cilia?
Abstract. Bardet–Biedl syndrome (BBS) is a ciliopathy resulting from defects in the BBSome, a conserved protein complex. BBSome mutations affect ciliary membrane composition, impairing cilia-based signaling. The mechanism by which the BBSome regulates ciliary membrane content remains unknown.
How is Bardet Biedl syndrome treated?
Bardet–Biedl syndrome is currently treated symptomatically focusing in particular on aggressive management of diabetes, hypertension, and metabolic syndrome to minimize the secondary impact that these conditions have on vulnerable organ systems already affected by BBS, in particular the eyes and kidneys (17).
What is Bardet Biedl syndrome symptoms?
Bardet Biedl Syndrome is a rare genetic disorder with highly variable symptoms which may include retinal degeneration, obesity, reduced kidney function, polydactyly (extra digits of the hands or feet) among many other features.
What is the life expectancy for BBS?
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.
Is Bardet-Biedl syndrome a learning disability?
Bardet-Biedl syndrome (BBS) is an autosomal recessive multisystemic genetic disorder characterised by six major defects including obesity, learning disability, renal anomalies, polydactyly, retinal degeneration and hypogenitalism. 19 BBS genes have been identified to date.
What is Curry syndrome?
Curry-Jones syndrome is a form of syndromic craniosynostosis characterized by unilateral coronal craniosynostosis or multiple suture synostosis associated with complete or partial agenesis of the corpus callosum, preaxial polysyndactyly and syndactyly of hands and/or feet, along with anomalies of the skin ( …
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.
How many people have Bardet Biedl?
In most of North America and Europe, Bardet-Biedl syndrome has a prevalence of 1 in 140,000 to 1 in 160,000 newborns. The condition is more common on the island of Newfoundland (off the east coast of Canada), where it affects an estimated 1 in 17,000 newborns.
What is Culler Jones syndrome?
Culler-Jones syndrome is a rare disease characterized by pituitary anomalies resulting in hypopituitarism, presence of extra fingers (polydactyly) and unusual facial features.
