Input: Consider Input: Question: Does presence of the full-length KIR2DS4 gene reduce the chance of rheumatoid arthritis patients to respond to methotrexate treatment?
Answer: Our results suggest that the response of RA patients with medium ESR values to MTX treatment may be dependent on the full-length KIR2DS4 gene.

Output: yes


Input: Consider Input: Question: Is liposarcomatous differentiation in malignant phyllodes tumours unassociated with MDM2 or CDK4 amplification?
Answer: This study examined molecular changes in the well-differentiated liposarcomatous components of MPT. Despite histological similarity to well-differentiated liposarcoma of soft tissues, liposarcomatous differentiation in MPT lacks the molecular phenotype characteristic of extramammary well-differentiated liposarcoma.


Output: yes
