Protein structure related information for QPRT
Relative protein structure stability change (ΔΔE) using Mupro 1.1
Mupro score denotes assessment of the effect of mutations on thermodynamic stability.
  (ΔΔE<0: mutation decreases stability, ΔΔE>0: mutation increases stability)
: nsSNV at non-LBS: nsSNV at LBS

nsSNVs sorted by the relative stability change of protein structure by each mutation
Blue: mutations of positive stability change. and red : the most recurrent mutation for this gene.

Differential gene expression and gene-gene network for QPRT
Differential gene expression between mutated and non-mutated LBS samples in all 16 major cancer types

Differential co-expressed gene network based on protein-protein interaction data (CePIN)
* Left PPI network was created from samples with mutations in the LBS of QPRT and the right PPI network was created from samples without mutations in the LBS of QPRT. Only genes with p-value < 0.05 are shown.
Red circle: input gene. Orange circle: LBSgene. Blue circle: other gene.
