HOXB13 and posterior cortical atrophy: By the same token, to examine the association of the recurrent mutation (G84E) in HOXB13 with PCa risk in a large international sample of PCa families, Xu et al. (2013) genotyped this mutation and 14 other SNPs in or flanking HOXB13 in 2,443 PCa families recruited by the International Consortium for Prostate Cancer Genetics (ICPCG).
