Brief description

A clear, everyday-language overview of this gene.

Retinitis pigmentosa (RP) due to mutations in the crumbs homologue 1 (CRB1) gene. It's a specific form of RP known as RP12, and is characterized by severe vision loss before age 20 and preserved para-arteriolar retinal pigment epithelium (PPRPE). CRB1 retinitis pigmentosa include the typical symptoms of retinitis pigmentosa (i.e., night blindness, gradual loss of peripheral vision, and progressive degeneration of photoreceptors). CRB1 mutations can also cause other retinal dystrophies, including Leber Congenital Amaurosis (LCA), which is the most severe case of early-onset retinal degeneration. The CRB1 gene encodes the Crumbs homolog-1 protein, this process is important for cell-to-cell contact, morphogenesis, and polarization of epithelial cells. At present, there's no cure for retinitis pigmentosa, but medications can help treat complications. A medical professional can diagnose and manage the condition to improve symptoms.

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.
