Thus we investigated genetic variants in 14 genes; Follicular stimulating Hormone Receptor (FSHR), A CGPR receptor (RAMP1), lymphotoxin alpha (LTA), Tumor Necrosis Factor (TNF), Synaptic Nuclei expressed (SYNE1), Potassium Channel Subfamily K Member 18 (KCNK18), Estrogen Receptor type 2 (ESR2), Cytochrome P450 Family 19, Subfamily A, Polypeptide 1 (CYP19A1), Estrogen Receptor 1 (ESR1), Progesterone Receptor (PGR), Nuclear Receptor Interacting Protein 1 (NRIP1) along with microRNA 890 (MIR890), microRNA 891A(MIRF981A) and microRNA 892A (MIR892A) in a population of MM cases and controls. This evidence concerns the gene TNF and Miyoshi myopathy.
