This genome-wide association study identified three significant genetic loci for oral tongue squamous cell carcinoma (OTSCC). Further research is needed to understand the genes involved in OTSCC development.
Area of Science:
- Genetics
- Oncology
Background:
- Oral tongue squamous cell carcinoma (OTSCC) is a significant subtype of head and neck cancer.
- Limited genome-wide association studies (GWAS) data exist for OTSCC, hindering the identification of its genetic underpinnings.
Purpose of the Study:
- To explore genetic associations for oral tongue squamous cell carcinoma (OTSCC) through a genome-wide association study (GWAS).
Main Methods:
- A GWAS was performed on 376 OTSCC cases from the FinnGen Data Freeze-12 dataset.
- Controls comprised 407,067 individuals without a history of malignancy.
- A Phenome-wide association study (PheWAS) was conducted on lead variants to assess co-associations with other cancers.
Main Results:
- Three genome-wide significant loci associated with OTSCC were identified at 5p15.33 (rs27067), 10q24 (rs1007771191), and 20p12.3 (rs1438070080).
- The lead variant rs27067 showed associations with prostate cancer and seborrheic keratosis, and a co-directional effect with melanoma.
Conclusions:
- The GWAS identified two novel genetic associations for OTSCC.
- Further investigation is required to pinpoint the specific genes at these loci contributing to OTSCC pathogenesis.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
