Latar Belakang: Stromal Cell-Derived Factor-1 SDF-1 mengkode protein SDF-1 yang berperan dalam angiogenesis dan metastasis sel kanker. Polimorfisme genetik SDF-1 G801A telah dilaporkan memiliki hubungan dengan kanker kepala leher KKL. Tujuan: Mendeteksi polimorfisme genetik SDF-1 G801A pada penderita KKL dan individu sehat populasi Indonesia. Metode: Sampel DNA tersimpan dari 50 penderita KKL dan 50 individu sehat dianalisis dengan metode PCR-RFLP dengan menggunakan enzim restriksi HpaII serta divisualisasi dengan elektroforesis. Hasil: Polimorfisme genetik SDF-1 G801A terdeteksi sebesar 54 pada kelompok penderita KKL dan 74 pada kelompok individu sehat. Simpulan: Polimorfisme genetik SDF-1 G801A terdeteksi pada penderita KKL dan individu sehat populasi Indonesia.

Introduction: Stromal Cell Derived Factor 1 SDF 1 gene encodes SDF 1 protein which plays roles in angiogenesis and metastasis of cancer cell. SDF 1 G801A genetic polymorphism has been reported to have an association with head and neck cancer HNC.

Aims: To detect SDF 1 G801A genetic polymorphism in HNC patients and healthy subjects of Indonesian population.

Methods: Stored DNA samples extracted from blood of 50 HNC patients and 50 healthy subjects were analyzed with PCR RFLP method using HpaII restriction enzyme and visualized by electrophoresis.

Results: There were 54 and 74 SDF 1 G801A genetic polymorphisms detected in HNC samples and healthy subject samples.

Conclusion: SDF 1 G801A genetic polymorphism was detected in HNC patients and healthy subject of Indonesian population.
