Gelsolin rs1078305 and rs10818524 polymorphisms were associated with risk of oral squamous cell carcinoma in a Chinese Han population

Background: Gelsolin (GSN) is one of the most abundant actin-binding proteins, and is involved in cancer development and progression.

Patients and methods: A hospital-based case-control study including 201 patients with OSCC and 199 healthy controls was conducted. Seventeen single-nucleotide polymorphisms (SNPs) of GSN were investigated by Sequenom Mass ARRAY and iPLEX-MALDI-TOF technology.

Results: Through comparison of the 17 SNPs on GSN gene between the two groups, SNP rs1078305 and rs10818524 were verified to be significantly associated with an increased risk of OSCC. For GSN rs1078305, the TT genotype was associated with increased risk for OSCC (OR?=?1.92, 95% CI?=?1.11–3.32, p?=?0.028). CT/TT variants were also associated with increased risk for OSCC compared to the CC genotype (OR?=?1.83, 95% CI?=?1.25–3.84, p?=?0.032).

Conclusion: The rs1078305 and rs10818524 SNPs of GSN were associated with increased risk for OSCC development in a Chinese Han population.
