Heterozygous AG genotype was associated with tumour size (OR = 3.67, P(Y) = 0.004), ER-negative tumours (OR = 3.25, P(Y) = 0.0028), triple-negative tumours (OR = 4.94, P(Y) = 0.015) but not menopausal status, PR and HER-2 status, local or distant metastasis. Homozygous GLCE genotypes (AA/GG) were more common for ER + PR + luminal A breast cancer (OR = 0.25, P(Y) = 0.031). Loss-of-heterozigosity was identified in 5 of 51 breast tumours and the loss of G allele was associated with the decreased GLCE expression. Epidemiologic data for the GLCE SNP in different racial/ethnic groups demonstrated high AG genotype rates as a risk factor not for breast cancer incidence but for poor prognosis of the disease. The obtained data suggest an involvement of GLCE rs3865014 in breast cancer development. Heterozygous AG genotype might be a risk factor for breast cancer susceptibility in Siberian women and is associated with aggressive ER-negative and triple-negative cancer subtypes.]]> Wed 19 Dec 2018 14:12:22 KRAT ]]>
