CHEK2 and breast cancer: We used BERT-based NER model to text mine the article (PMID:29271107) and identified the sentence containing a variant “The novel c.1232G > A is a truncating and function disrupting mutation of the CHEK2 gene, identified in an early onset breast cancer proband.” By searching the key word “cosegregate*” in its preceding, current and subsequent sentences, the evidence of “The high number of breast cancers observed in this family, cosegregation of the variant with the disease and its LOH in the breast cancer tissue, strongly suggest this is a breast cancer predisposing allele.” was spotted.
