SNRPD1 and breast cancer: The prognostic value of SNRPD1 on breast cancer outcome was identified with statistical significance using multiple public data sets which, however, was not found for SNRPE. The rare allele of one quantitative trait loci (eQTL) of SNRPD1, rs6733100, was revealed to confer a protective effect on patient outcome using data retrieved from The Cancer Genome Atlas (TCGA).
