Diagnostic Utility

HLA class I (HLA-A, B and C) expression on the sarcolemma is upregulated in idiopathic inflammatory myopathies, such as dermatomyositis, polymyositis and inclusion body myositis, and HLA class I immunostain has been reported to be a sensitive marker for evaluating these inflammatory myopathies.
