Cancer Variant Interpretation Group UK (CanVIG-UK) was established in 2017. Its initial purpose was to improve consistency in the interpretation of genetic data from cancer susceptibility genes (CSGs) in the NHS laboratories across the UK. Still convening for monthly national meetings, CanVIG-UK develops national consensus guidance and delivers training and education, among other key activities. In a survey of 163 CanVIG-UK members in November 2025, 96.9% rated the consensus recommendations as “extremely”/”very useful” and 61.4% reported using it at least weekly. Through the responses to this survey, the continuing value of CanVIG-UK to the UK clinical-laboratory community was clearly demonstrated. (https://jmg.bmj.com/content/early/2026/07/15/jmg-2026-111625)
