Brief description

A clear, everyday-language overview of this gene.

Retinitis pigmentosa (RP) is a symptom of Bardet-Biedl syndrome type 2 (BBS2), an inherited disorder that affects the retina and other parts of the body. People with BBS2-related RP experience a gradual decline in vision, often starting with night blindness. Other symptoms include decreased peripheral vision, loss of visual acuity, and reduced color discrimination. BBS2 is characterized by a number of other features, including polydactyly, renal disease, hypogonadism, obesity, dysmorphic features, and variable degrees of cognitive impairment. At present, there's no cure for RP, but treatments can help people make the most of their vision. These include low vision aids, rehabilitation programs, vitamins, and supplements. Gene-specific therapies may also be an option, but patients need to know the specific genetic cause of their disease. The majority of reported BBS cases are linked to mutations found in BBS1 and BBS10 genes.

Support, accessibility and family guidance(the same for every gene)

This guidance applies to anyone living with an inherited retinal condition, whichever gene is involved. Anything specific to this gene is in the section above.

Ask before helping: People differ widely in what assistance they want, and it changes by task and by day. Asking first respects that, and avoids help that gets in the way.
Low-vision rehabilitation: Low-vision specialists work on practical skills and tools for the sight someone has — lighting, contrast, magnification, orientation and mobility.
Accessible technology: Screen readers, magnification, high-contrast modes and voice control are built into phones and computers. Small settings changes often help sooner than new equipment.
School and work: Accommodations are often available well before vision loss is severe. Starting the conversation early usually makes it easier.
Emotional and community support: A genetic result affects the whole family. Connecting with others living with RP helps people feel less alone with it.
Genetic counselling: A genetic counsellor can explain what a result means for relatives, and what testing options exist, without anyone being pushed into a decision.
