## Summary

The North Thames Genomic Medicine Service states that it works to provide equitable access to genomic testing for people across North London, Hertfordshire and Mid and South Essex, and has a section for patients and the public; in 2026 it announced new genomic testing pathways for patients with a cancer of unknown primary.
