Similarly, a 19-gene combination, (EPR1, CREB3L1, BGN, CXCL10, UBE2S, INHBA, CEP55, BUB1, KIFC1, CDC45, SPATA17, CA12, CILP2, PTTG1, ADAMTS14, CLEC5A, FGD3, TNFRSF18, NEIL3), has been identified that could distinguish the MD group from the WD group with 94.2% classification accuracy (95.0% sensitivity and 92.2% specificity). This evidence concerns the gene PTTG1 and Menkes disease.
