These findings were supported by another study in mesotheliomas that showed that homozygous deletion of CDKN2A was associated with loss of expression of mTAP in all cases studied, resulting in 100% specificity and 74% sensitivity of loss of expression of mTAP for homozygous deletion of CDKN2A [48]. The gene discussed is CDKN2A; the disease is mesothelioma.
