A clear, everyday-language overview of this gene.
A mutation in the ADP ribosylation factor-like GTPase 3 (ARL3) gene can cause retinitis pigmentosa (RP), a disease that leads to vision loss. A missense variant in ARL3 can cause non-syndromic RP. For example, the c.269A>G (p.Tyr90Cys) variant has been found in two unrelated families. ARL3 is found in the cilium of the retina. It helps transport cargo complexes through the cilium, which contain proteins like kinase and transducin. ARL3 is regulated by retinitis pigmentosa 2 (RP2) and ARL13b. RP2 is a GTPase activating protein (GAP) for ARL3, while ARL13b is a GTP-exchange factor (GEF).
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.
