Presentation
OD, FAAO CASE REPORT Abstract Author Information Authors This case report describes the presentation of a patient with Bardet-Biedl syndrome. [journals.lww.com]
Although triallelism (three deleterious alleles in the same patient) has been described in some BBS families, we have to date no evidence that this is the case in the present family. [ncbi.nlm.nih.gov]
Since the age of 1 month, she presented recurrent respiratory infections and bronchiolitis, leading to the diagnosis of infantile asthma. She also presented recurrent ENT infections and benefited from adenoidectomy and myringotomy. [karger.com]
Molecular genetic testing is available on a clinical basis for p.M390R, the common mutation in BBS1 that is present in approximately 18%-32% of individuals with BBS and p.C91LfsX4 (also known as C91fsX95), a common mutation in BBS10, that is present in [omicsonline.org]
Rumination was present at the age of two but disappeared spontaneously a few years later. This condition recurred at the age of nine, but faded out again at a later stage. [nature.com]

Weight Gain
Birth weight is typically normal but significant weight gain beigns within the first year. Renal disease is a major cause of morbidity and mortality. There is considerable interfamilial and intrafamilial variability in the clinical presentation. [dnatesting.uchicago.edu]
Weight is usually normal at birth but weight gain is quickly evident through the first year of life in as many as 90% of people with BBS. [rarediseases.org]
Abnormal weight gain typically begins in early childhood and continues to be an issue throughout life. [ghr.nlm.nih.gov]
Hyperphagia Hyperphagia due to insatiable appetite may lead to life-threatening weight gain, or may lead to stomach necrosis and rupture. Weight gain may be very rapid and occur even on a low-calorie diet. [medicalhomeportal.org]
Bardet-Biedl is a syndrome (set of related attributes) caused by a genetic mutation and characterized by the eye condition known as cone-rod dystrophy, in addition to a variety of features that may include abnormal weight gain in the trunk (and related [familyconnect.org]

Recurrent Respiratory Infections
Since the age of 1 month, she presented recurrent respiratory infections and bronchiolitis, leading to the diagnosis of infantile asthma. She also presented recurrent ENT infections and benefited from adenoidectomy and myringotomy. [karger.com]
Respiratoric
-
Respiratory Insufficiency
The neonatal period was complicated with respiratory insufficiency (the child was intubated on the first day of life and stayed on mechanical ventilation for nine days) and a generalized infection with staphylococci. [omicsonline.org]
Cardiovascular
-
Tachycardia
During hospitalization a renal insufficiency was detected, along with ionic disorders and a tachycardia of atrial origin. [omicsonline.org]
Face, Head & Neck
-
Pointed Chin
She exhibited dysmorphic features, including an upslanted palpebral fissure, hypertelorism, pointed chin and high arched palate as well as postaxial polydactyly of the right hand and left foot, polycystic kidneys and an atrial septum defect that was closed [nature.com]
Neurologic
-
Sleep Disturbance
She exhibited daily emotional outbreaks and sleep disturbances that required some sedative drugs, such as carbamazepine, cyproheptadine and risperidone, since early childhood. [nature.com]
-
Dysphasia
A speech examination identified congenital developmental dysphasia caused by endogenic factors. The girl had a perceptive-expressive disorder with a speech development delay. [omicsonline.org]
Urogenital
-
Clitoromegaly
During the subsequent diagnosis a 2 nd grade virilisation of genital organs was observed: clitoromegaly, an urogenital sinus, and hydrocolpos. For this reason urine steroid profile was analysed, which excluded blocks of adrenal steroidogenesis. [omicsonline.org]
-
Imperforate Hymen
It is caused by the distension of the uterine cavity and the vagina due to an accumulation of cervical gland secretions stimulated by maternal and placental estrogen in the presence of the vaginal septation or atresia or an imperforate hymen [ 6, 16 ] [omicsonline.org]
Workup
DIAGNOSIS AND TREATMENT The most important consideration in the workup of anovulation is to determine the patient’s goals. [glowm.com]
Microbiology
-
Chlamydia
When it became clear that BBS genes code for proteins implicated in cilia assembly or function, 12 comparison of sequenced genomes allowed selection of candidate genes that have orthologs in ciliated organisms (vertebrates, drosophila, C. elegans, chlamydia [doi.org]

Giardia Lamblia
lamblia, an organism that does not contain well-conserved orthologs to known BBS genes. 13 This combination of homozygosity mapping and comparative genomics allowed the identification of BBS3, BBS5 and BBS9. 5, 6, 8, 13 Single sibship consanguineous [doi.org]

Diagnosis of the condition is important for visual prognosis and low vision management. The renal disease often goes undetected until specific radiological testing is done after diagnosis of Bardet-Biedl syndrome. [journals.lww.com]
Common Features of the Disorder Eye problems (e.g. progressive vision loss) Obesity Intellectual disability Developmental delays Extra fingers or toes Kidney dysfunction Genital anomalies Male infertility Prognosis Most individuals are not affected at [evolvegene.com]
Visual prognosis is poor, and the mean age of legal blindness is 15.5 years. Birth weight is typically normal but significant weight gain beigns within the first year. Renal disease is a major cause of morbidity and mortality. [dnatesting.uchicago.edu]
Etiology
Etiology The wide clinical spectrum observed in BBS is associated with significant genetic heterogeneity. To date, mutations in 12 different genes ( BBS1 to BBS12 ) have been identified as being responsible for this phenotype. [orpha.net]

On the basis of electroencephalography, disorders with epileptic etiology were ruled out. Ophthalmological tests showed bilateral hyperopic astigmatism. [omicsonline.org]
The etiology is still unknown, but it is described in the literature as 35% to 48% of parental consanguinity in patients with this syndrome. [dentalnews.com]

Pathophysiology
These three genes are characterized by unusually rapid evolution and are likely to perform ciliary functions specific to vertebrates that are important in the pathophysiology of the syndrome, and together they account for about one-third of the total [ncbi.nlm.nih.gov]
Pathophysiology The detailed biochemical mechanism that leads to BBS is still unclear. The gene products encoded by these BBS genes, called BBS proteins, are located in the basal body and cilia of the cell. Using the round wormC. elegans as a model [de.slideshare.net]
