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 [scielo.br]
Entire Body System

Weight Gain
His daily dietary intake consisted mostly of fruits, vegetables, and 12 ounces of breast milk, as carbohydrates were restricted in an attempt to limit weight gain. [nature.com]
Additionally, individuals with this condition may be born with polydactly (extra fingers or toes) and develop issues with weight gain that can lead to childhood obesity. [diseaseinfosearch.org]
Abnormal weight gain typically begins in early childhood and continues to be an issue throughout life. [ghr.nlm.nih.gov]
With low levels of thyroid stimulating hormone, people will experience many different symptoms: fatigue, sensitivity to cold, poor ability to concentrate, weight gain, constipation, shortness of breath. [rarediseases.org]
Patient interview questions should focus on eating and drinking habits, the pattern of weight gain, behavior, and the achievement of developmental milestones. [nutritionhouse.com]

Asymptomatic
In most of the cases, only giving birth to a symptomatic child defines a family as being at genetic risk, with 25% chance of having another child with the disease and 50% of having offspring that are asymptomatic carriers [ 5, 6 ]. [omicsonline.org]
The recruited individuals consist of both affected siblings (IV-4 and IV-5), one unaffected brother (IV-6) and an asymptomatic carrier mother (III-2). Pedigree analysis revealed an autosomal recessive mode of disease segregation (see Fig. 1 ). [bmcmedgenet.biomedcentral.com]
Respiratoric

Pneumonia
Since her birth, the child had frequent occurrences of bronchitis and pneumonia, as well as persistent auscultatory changes such as wheezing and buzz. Based on a bronchoscopic material ciliary dyskinesia was diagnosed. [omicsonline.org]

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]
Musculoskeletal

Long Arm
The BBS10 gene is located on the long arm of the chromosome 12(12q21.2) [ 7, 9 ]. The BBS10 gene provides instructions for making a protein that is found in many types of cells. [omicsonline.org]

Dolichocephaly
During the 26 th week of the pregnancy, ultrasonography showed slight dolichocephaly, an abnormal facial profile - low nasal bridge ( Figure 1 ), hypertelorism ( Figure 2 ). There was a noticeable nuchal edema, with the nuchal fold equalling 11 mm. [omicsonline.org]

Low Set Ears
Examination revealed a round face, low-set ears with fleshy lobes, a right ear pit (Fig. 1 ), a 2 1 cm café-au-lait spot on the right chest, and postaxial polydactyly on his right foot (Fig. 1 ). [nature.com]

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]

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]

Prognosis [ 2 ] Prognosis is very poor where renal failure occurs. Prevention [ 4 ] Genetic counselling and pre-conception genotyping of family members may be worthwhile if the genetic mutation has been identified in a family member. [patient.info]
Prognosis The renal abnormalities are the main life-threatening manifestations because they can lead to end-stage renal failure and require renal transplantation. [orpha.net]
Diagnosis of the condition is important for visual prognosis and low vision management. Ophthalmologic and electrophysiological examinations are essential for confirmation and correct diagnosis of BBS (5). [scielo.br]
Diagnosis of this syndrome is based mostly on clinical criteria and, due to a better prognosis, requires a priori exclusion of BBS [ 6, 15 ]. One of the known genes responsible for this syndrome is the MKS gene. [omicsonline.org]
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]
Segregation mapping by STR markers in the complete family, through STR markers, confirmed the inheritance of the homozygous region with disease etiology. [bmcmedgenet.biomedcentral.com]
During the last 12 months, the first three of at least six BBS genes have been identified, providing us for the first time with the ability to formulate hypotheses regarding the molecular etiology of the disorder. [academic.oup.com]
