rs25487

Chromosome : 19 , Position: 43551574
Most conditions are affected by anywhere from hundreds to millions of genetic variants (SNPs). A single SNP usually has a minor contribution to a person’s overall genetic risk for a certain condition. That is why you shouldn't consider or act on a SNP in isolation. Instead, we use SNPs to determine polygenic risk scores (PRSs), which are the basis of most health reports.

Summary

rs25487 is a SNP also known as Gln399Arg, located in the DNA repair gene XRCC1. The (A) allele encodes the Gln amino acid.

In one study of ~1000 Caucasians, the rs25487(A;A) genotype had significantly reduced risk of both basal cell [BCC; odds ratio 0.7, CI: 0.4-1.0] and squamous cell cancer (SCC; odds ratio 0.6, CI: 0.3-0.9).[PMID 11782372]

In a study of ~300 Koreans, rs25487(A;G) and (G;G) genotypes had an approximately 2-fold increased risk of basal cell cancer compared to rs25487(A;A) individuals (adjusted odds ratio 2.324, CI: 1.11-4.86, respectively).[PMID 17355263]

A meta-analysis of 10+ studies found that rs25487(G) carriers had increased childhood risk of acute lymphoblastic leukemia among Asians under the dominant (odds ratio 2.11, CI: 1.502.97, p<0.0001) as well as other models. No association was found in Caucasians between rs25487 and risk of either myeloid or lymphocytic leukemia.[PMID nil]

A small study (113 cases) of Hispanics with non-small cell lung cancer found an odds ratio of 1.52 per rs25487(A) allele (CI: 1.01-2.28). [PMID 19029194]

A study of 200 patients with Hodgkin disease compared to controls concluded that some risk was associated with this SNP, along with SNPs in other genes involved in DNA repair genes. rs25487(A;G) individuals were at 1.77x increased risk (CI: 1.16-2.71) for the disease.10.1002/cncr.24205

[PMID 21216841] A meta-analysis concludes that this SNP is not associated with risk of gastric cancer.

More Information

rs25487 is located in the DNA repair gene XRCC1. It is significantly associated with skin cancer.

In patients with lymphoma undergoing autologous stem cell transplant (ASCT), carriers of a mutant ''T'' allele had a two-fold higher risk of death than those with the wild-type genotype. In addition, patients harboring one or two copies of the ''T'' allele (CT/TT) were 4.5-fold more likely to develop therapy-related acute myeloid (t-AML) [R]. 

Statistically significant association with breast cancer risk was observed for homozygous mutant TT (OR 2.91) and combined mutant (TT + TC) (OR 1.41) genotypes [R]. 

The minor allele ''T'' was significantly associated with pancreatic cancer (PC) risk in the per-allele model (odds ratio = 1.29, P = 0.043) [R]. 

The ''T'' allele was associated with reduced response rate (RR) to platinum-based chemotherapy in all gastric and colorectal cancer patients (T/C + T/T vs C/C OR, 0.73) and in Asians (OR, 0.62) but not in Caucasians (OR, 0.92) [R].

TT genotype was associated with worse breast cancer-specific and overall survival in patients after postoperative radiotherapy and adjuvant chemotherapy for breast cancer (p=0.031 and p=0.030, respectively) [R]. 

The genotype T/T was correlated with a higher risk of bladder cancer (BC)  in the Russian cohort (OR = 2.29, p = 0.0082) and an increased incidence of kidney cancer (KC) in the Bashkir group (OR = 4.06, p = 0.05) [R].

The presence of the T/T genotype reduced the risk of Alzheimer's Disease (AD) (OR = 0.485) [R]. 

''T'' allele was significantly associated with progression disease (PD) to EOF (p = 0.002), and gastric cancer patients with TT genotype had significantly poorer progression-free survival (PFS) (p = 0.001) and overall survival (OS) (p = 0.041) compared with patients with the C allele (CC + CT) [R]. 

The presence of at least one T allele (TT/TC) was associated with unfavorable prognosis (P = 0.005) of hepatitis B virus-related hepatocellular carcinoma. Moreover, T allele (TT/TC) carriers were significantly associated with high risk of vascular invasion (P = 0.025) and regional invasion (P = 0.005) [R]. 

TC geno-type was associated with a higher incidence of lung cancer compared with the CC genotype [R].
