Presentation
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]

Case presentation The patient was diagnosed with RP at the age of 6 years. She had some difficulty in social interactions and pre-obesity, but no polydactyly. [rrtjournal.biomedcentral.com]
If an individual receives one normal allele and one mutated allele (that is responsible for causing illness), the person will be a carrier for the disease, but usually will not present with symptoms. [rarediseases.org]
Entire Body System
- Weight Gain
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]

These features include the classic cone-rod dystrophy and renal abnormalities previously discussed, as well as less commonly seen, anosmia (inability to smell), hearing loss, and situs inversus. [rarediseases.org]

Standard Therapies Treatment The primary treatment goal for patients with BBS involves treating the specific symptoms affecting each individual. [rarediseases.org]
Moreover, some forms of symptomatic treatment may make phenotypes more difficult to clearly discern. [rrtjournal.biomedcentral.com]
Prognosis
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]

Prevention
Good diet management can prevent the weight-related problems that manifest in later life. Consulting with a primary care physician and a dietician can help in planning for adequate nutrition and prevention of excess weight gain. [rarediseases.org]
