Abstract

Oral squamous cell carcinoma (OSCC) is a common subtype of head and neck squamous cell carcinoma (HNSCC), but the pathogenesis underlying familial OSCCs is unknown. Here, we analyzed whole-genome sequences of a family with autosomal dominant expression of oral tongue cancer and identified proto-oncogenes VAV2 and IQGAP1 as the primary factors responsible for oral cancer in the family. These two genes are also frequently mutated in sporadic OSCCs and HNSCCs. Functional analysis revealed that the detrimental variants target tumorigenesis-associated pathways, thus confirming that these novel genetic variants help to establish a predisposition to familial OSCC.
