<jats:p>The enzyme uridine diphospho glucuronosyltransferase 2B17 (UGT2B17), localized on chromosome band 4q13, glucuronidates various endogenous compounds and xenobiotics, in particular androgens. The gene UGT2B17 shows a remarkable copy number variation (CNV) and, of all genes, by far the highest difference in mRNA expression between the Asian and Caucasian normal populations. Several reports indicate a role of UGT2B17 in cancer progression and moreover, in drug response. Furthermore, UGT2B17 has immunologic effects as a minor histocompatibility antigen. However, its role in multiple myeloma has not yet been investigated.</jats:p>

<jats:p>Distribution of the CNV in multiple myeloma was 15.5% double deletion (del/del), 43.0% heterozygous (ins/del) and 41.5% wild type (ins/ins).

Median overall survival (OS) was 43.9 months for del/del compared to 72.5 months in patients with ins/ins or ins/del (not significant). There was no significant difference in PFS or OS between wild type and heterozygous genotype.
