In contrast, our findings in the LFS family indicate that TP53 intron 1 can also occur in the germline and once such a SV is present as a germline alteration it can give rise to not only OS but multiple types of cancer, including adenocarcinoma, meningioma, astrocytoma, colon cancer, basal cell and squamous cell carcinoma of the skin. The gene discussed is TP53; the disease is meningioma.
