Novel p53 splicing site mutation in Li‐Fraumeni‐like syndrome with osteosarcoma
2013
We describe a 15-year-old girl with a novel germline p53 splice site mutation who developed an osteosarcoma. She received several cycles of chemotherapy with complete resection of the primary tumor without amputation, and has maintained remission for 18 months. Li-Fraumeni-like syndrome was suspected based on familial history. Sequence analysis revealed the presence of a novel germline p53 gene mutation resulting in a G to A transition at position +1 at the donor splice site of intron 6, creating a 6 amino acid insertion. This case provides interesting insight into the phenotype-genotype correlation in LFL syndrome with a TP53 splicing mutation.
