We also found that the prevalence of rheumatoid factor, antinuclear antibody, and anti-Ro/SS-A antibody did not differ among patients with HTLV-I-associated myelopathy with SS, SS positive for the anti-HTLV-I antibody, and SS negative for the anti-HTLV-I antibody [15]. The gene discussed is CALR; the disease is Myelopathy.
