Figure 1From: Presence of the full-length KIR2DS4 gene reduces the chance of rheumatoid arthritis patients to respond to methotrexate treatment Telomeric KIR haplotype profiles in MTX good responder and poor responder RA patient groups. Grey box: gene presence; white box: gene absence. Estimation of KIR gene frequency based on haplotype distributions shown for KIR3DL1 – 81.5% and 78.7%, for KIR3DS1 18.6% and 21.5%, for KIR2DS5 15.9% and 18.1%, for KIR2DS1 22.4% and 26.0%, for KIR2DS4f 16.4% and 20.3%, for KIR2DS4d 63.3% and 56.3%, in good responder and poor responder groups, respectively.Back to article page
