# Retinitis pigmentosa genetic testing and counseling

Genetic testing and counselling are central to modern care for retinitis pigmentosa (RP), a heterogeneous group of inherited retinal dystrophies. They help clarify the specific diagnosis, inheritance pattern, and eligibility for emerging therapies.

## Role of Genetic Testing

Next‑generation sequencing panels or whole‑exome tests analyse many retinal disease genes simultaneously.

- Identifying the causative variant confirms the diagnosis and distinguishes RP from other inherited retinal diseases.
- Results define the inheritance pattern (autosomal dominant, autosomal recessive, X‑linked, or mitochondrial).
- Genotype information is increasingly required for entry into clinical trials and gene‑specific treatments.
- Testing is usually offered alongside pre‑test and post‑test counselling to explain implications and limitations.

## Genetic Counseling

Specialist counselling supports patients and families in understanding and acting on genetic information.

- Relatives can be offered predictive or confirmatory testing when appropriate.
- Discussions cover recurrence risks, family planning options, and psychological impact.
- Patients are signposted to support groups, registries, and research studies.
- Results are integrated with clinical findings to guide prognosis and long‑term monitoring.
