Thyroid‐associated genetic polymorphisms in relation to breast cancer risk in the Malmö Diet and Cancer Study
AssociationN=4,058Jasmine Brandt et al.(2018)· International Journal of Cancer

This prospective nested case-control study examined 17 single nucleotide polymorphisms related to free thyroxine (fT4) and thyroid peroxidase antibody (TPO-Ab) levels in 865 breast cancer cases and 3,193 controls from the Malmö Diet and Cancer Study. The main findings identified fT4-related SNPs rs2235544 (DIO1 gene, OR for breast cancer risk in low fT4 women) and rs6485050, as well as TPO-Ab-related SNPs rs11675434, rs3094228, rs1033662, rs301806, and rs2071403 as potentially associated with breast cancer risk. The most promising association was rs2235544 (DIO1), where the C allele was associated with lower fT4 levels and increased breast cancer risk, particularly in women with low fT4 levels, suggesting a potential causal relationship.

About HLA-DPB1

HLA-DPB belongs to the HLA class II beta chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DPA) and a beta chain (DPB), both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The beta chain is approximately 26-28 kDa and its gene contains 6 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and exon 5 encodes the cytoplasmic tail. Within the DP molecule both the alpha chain and the beta chain contain the polymorphisms specifying the peptide binding specificities, resulting in up to 4 different molecules.
