RESUMEN
Objective To investigate the relationship between transforming growth factor gene (TGF) single nucleotide poly‐morphism (SNP) and multiple myeloma (MM) .Methods The case control study was performed ,55 patients with MM and 55 healthy controls were selected .The genotype and allele detections were performed by adopting the polymerase chain reaction (PCR) and the ligase detection reaction (LDR) respectively .Then the sequencing based typing was further conducted .Results There were no statistically significant differences in the two loci genotype frequencies ,allele frequencies and genotype frequencies in joint hap‐loid typing between the MM group and the control group(P>0 .05) .Conclusion SNP of TGF gene has no obvious correlation with the occurrence of MM and subtypes.
