In addition, we detected several proteins with expression levels higher in MM cells, including Fc receptor-like 2 and 5 (FCRL2 and 5), receptor tyrosine kinase like orphan receptor 2 (ROR2), signaling lymphocytic activation molecule family member 1 (SLAMF1) and lysosomal associated membrane protein 3 (LAMP3) (Fig. 7b). This evidence concerns the gene SLAMF1 and Miyoshi myopathy.
