Certain C-reactive protein (CRP) gene polymorphisms, specifically +942G>C and 1846C>T, are linked to an increased risk of developing cancer, particularly colorectal cancer.
Area of Science:
- Genetics
- Oncology
- Molecular Biology
Background:
- Elevated C-reactive protein (CRP) levels are implicated in human cancer development.
- Genetic variations (polymorphisms) within the CRP gene may influence cancer susceptibility.
Purpose of the Study:
- To investigate whether CRP gene polymorphisms (+942G>C and 1846C>T) modify inherited susceptibility to cancer.
- To systematically review and meta-analyze existing studies on CRP gene polymorphisms and cancer risk.
Main Methods:
- Systematic literature search for case-control studies on CRP gene polymorphisms and cancer.
- Meta-analysis of 8 eligible studies.
- Analysis of specific genotypes (+942G>C and 1846C>T) and their association with cancer risk.
Main Results:
- The CC genotype at the +942G>C locus was associated with a nearly 4-fold increased cancer risk.
- A significant association was observed for colorectal cancer.
- The 1846C>T polymorphism showed an increased cancer risk with the TT genotype (OR=1.15-1.17).
- These associations were particularly noted in Caucasian populations.
Conclusions:
- Both +942G>C and 1846C>T polymorphisms in the CRP gene may play a role in cancer susceptibility.
- CRP gene variants could be potential biomarkers for cancer risk assessment.

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.
