There are five single-nucleotide polymorphisms reported within the CCL2 locus (http://www.ncbi.nih.gov/SNP/); however, only two of these were within the region screened for mutations and each of these had minor allele frequencies of less than 0.5% so it is not surprising that these were not detected within the 94 ovarian cancer samples we screened. The gene discussed is CCL2; the disease is ovarian cancer.
