Brief description

A clear, everyday-language overview of this gene.

CA4 retinitis pigmentosa is a type of retinitis pigmentosa (RP) caused by a mutation in the carbonic anhydrase IV (CA4) gene, also known as the RP17 locus. A mutation in the CA4 gene can cause RP. The CA4 gene encodes a protein that's expressed in the choriocapillaris of the eye. One mutation identified in a patient with RP is R69H, which impairs the pH recovery of the retina. As mentioned many times on this site, RP is a group of inherited eye diseases that cause the retina's light-sensing cells to gradually deteriorate, leading to vision loss.

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.
