📋 Overview

The NHS Genomic Medicine Service delivers whole genome sequencing for selected rare disease and cancer indications, integrating with genomic tumour profiling and targeted therapies.

🔬 Basic Science

The NHS Genomic Medicine Service delivers whole genome sequencing for selected rare disease and cancer indications, integrating with genomic tumour profiling and targeted therapies.

🏥 Clinical Relevance

Direct-to-consumer testing raises issues of accuracy, interpretation and consent.

🧪 Investigations

Investigation depends on clinical context: relevant blood tests, imaging, and specific genetic or histopathological tests as appropriate. Refer to specialist services where indicated.

💊 Management

Management is condition-specific and typically multidisciplinary, combining medical therapy, surgical intervention where appropriate, supportive care, and family/genetic counselling.

  • The NHS Genomic Medicine Service offers WGS for selected rare disease and cancer indications.
  • Targeted therapies require tumour molecular profiling (e.g. EGFR, BRAF, HER2).
  • Companion diagnostics link a specific test to a specific therapy.
  • Direct-to-consumer testing is generally less rigorously regulated and interpreted.
  • Genomic medicine raises issues of consent, data sharing and incidental findings.
