The results of a sufficiently large number of GWAS indicate associations of SNPs located in the area of the STON1-GTF2A1L, GTF2A1L, and STON1 genes with such BC-significant BMI-related signs as height [122], weight [123], waist circumference [124], waist-to-hip ratio [125,126,127,128,129], gluteal-femoral adipose tissue volume [130], body shape index [128], BMI [123,126,127,129,131,132,133,134], and body size in adults [135]. Here, GTF2A1L is linked to breast cancer.
