Moreover, WBMRI has recently been shown to be of particular interest in TPM2-related myopathies (Jarraya et al., 2012) an in certain forms of distal arthrogryposis such as DA10 (Stevenson et al., 2006) or arthrogryposis due to ECEL1 mutations (Dieterich et al., 2013) but has not been used in DA2B yet. The gene discussed is TPM2; the disease is myopathy.
