In the multivariate statistical analysis, we showed that the expression of PDLIM1P4 together with 8 clinical and genetic risk factors divided MM patients into different level risk groups for PFS. In the case of OS, two lncRNAs, PDLMI1P4 and ENSG00000249988, together with 8 different clinical and genetic risk factors stratified MM patients into different OS risk groups. This evidence concerns the gene PDLIM1P4 and Miyoshi myopathy.
