(G;G) 0 common in clinvar

This genotype is associated with Li Fraumeni syndrome. However, we have noticed a statistically unlikely increase in the number of customers of one DNA testing company who's genotype for this SNP is being incorrectly reported. This is likely to be a technical error - you probably actually carry the completely normal, unmutated genotype for this SNP. You should seek to have a clinically validated test carried out if you have either a significant family history of cancer or if you have any concerns about this.
