5-Amino-4-Imidazolecarboxamide Ribonucleotide Transformylase/IMP Cyclohydrolase Polymorphisms Affect the Susceptibility to Multiple Myeloma.

Objective The upregulation of 5-amino-4-imidazolecarboxamide ribonucleotide transformylase/IMP cyclohydrolase (ATIC) may affect tumorigenesis and multiple myeloma (MM) development. Materials and Methods A total of 97 patients with MM and 102 healthy control patients were included in the study. The SNaPshot technique was used to detect the ATIC gene polymorphisms. Linkage disequilibrium (LD) and haplotype analyses were conducted using SHEsis software. Results The genotype distribution or allele frequency of rs3772078 and rs16853834 was significantly different between the patients with MM and the healthy control patients (all P  <.05). The rs16853834 A allele, rs3772078 CT genotype, and C allele were associated with a decreased risk of MM (all P  <.05). Five single-nucleotide polymorphism combinations showed strong LD. Three haplotypes were associated with MM risk (all P  <.05). We found that ATIC rs7604984 was significantly associated with serum lactate dehydrogenase levels (P  = .050). Conclusion We determined that the rs3772078 and rs16853834 polymorphisms are associated with a decreased risk of MM. [ABSTRACT FROM AUTHOR]
