Association study reveals novel risk loci for sporadic inclusion body myositis. (24th February 2017) - Johari, M.
Abstract : Background and purpose: The aim was to identify potential genetic risk factors associated with sporadic inclusion body myositis (sIBM). Methods: An association based case−control approach was utilized on whole exome sequencing data of 30 Finnish sIBM patients and a control cohort ( n = 193). A separate Italian cohort of sIBM patients ( n = 12) was used for evaluation of the results. Results: Seven single nucleotide polymorphisms were identified in five genes that have a considerably higher observed frequency in Finnish sIBM patients compared to the control population, and the previous association of the genetic human leukocyte antigen region was confirmed. Conclusions: All seven identified variants could individually or in combination increase the susceptibility for sIBM.
