Moreover, the BC-risk allele C rs10454142 was associated with a lower level of three genes’ expression (STON1-GTF2A1L, GTF2A1L, and RP11-460M2.1) and splicing of the PPP1R21 gene in adipose tissue, and also, along with this, this allele has been associated with a higher level of three genes’ splicing, namely STON1, STON1-GTF2A1L, and GTF2A1L, in adipose tissue. Here, GTF2A1L is linked to breast cancer.
