In order to evaluate whether genotypes in the DEAR1 gene were associated with some specific tumoral characteristics, a multinomial logistic regression was carried out between DEAR1 genotypes and 5 clinical and histopathological tumor characteristics (histology, histological grade, ER status, PR status, and HER2 status) (data are shown in Tables 4 and 5). The gene discussed is ERBB2; the disease is neoplasm.
