After publication of the original article , it came to the authors’ attention that a reference was omitted from the Background. The reference should have been inserted as  and is the following:
Vedeld HM, Andresen K, Eilertsen IA, Nesbakken A, Seruca R, Gladhaug IP, Thiis-Evensen E, Rognum TO, Boberg KM, Lind GE: The novel colorectal cancer biomarkers CDO1, ZSCAN18 and ZNF331 are frequently methylated across gastrointestinal cancers. Int J Cancer 2015, 136:844–853.
The last paragraph of the Background should have read as follows:
“Zinc finger protein 331 (ZNF331) was first identified from thyroid tumors . It is also known as RITA (rearranged in thyroid adenoma), ZNF361, and ZNF463 . The ZNF331 gene is located at chromosome 19q13.42, a region in which loss of heterozygosity (LOH) was detected in prostate cancer . In our previous study, we found that the ZNF331 gene is frequently methylated in human esophageal squamous cell cancer (ESCC) and it serves as a tumor suppressor in ESCC . It was reported that the high methylation frequency of ZNF331 was found in some types of gastrointestinal cancer including CRC . But the function of ZNF331 in human CRC remains unclear. In this study, we analyzed the epigenetic regulation and the function of ZNF331 in human CRC.”
