To identify effects of the ELL2 MM risk allele on gene expression, we generated mRNA-sequencing data for CD138+ plasma cells from bone marrow samples from 185 MM patients from Sweden and Norway, and genotyped these samples for one of the linked MM risk variants at the ELL2 locus (rs3815768; Supplementary Fig. 1a). Here, ELL2 is linked to Miyoshi myopathy.
