<unk>  can be characterized by cutaneous pigmentation, premature graying, dystrophy of the nails, leukoplakia of the oral mucosa, continuous lacrimation due to atresia of the lacrimal ducts, often thrombocytopenia, anemia, testicular atrophy in the male carriers, and predisposition to cancer. Many of these symptoms are characteristic of geriatrics, and those carrying the more serious forms of the disease often have significantly shortened lifespans. Also, liver abnormalities are associated with this syndrome, Nodular Regenerative Hypoplasia of the liver, although rare, it is one of many manifestations of liver disorders short telomeres can cause. Predisposition to cancer Susceptibility to cancer seems counterintuitive because in many known cancers reactivation of telomerase is actually a required step for malignancy to evolve (see telomere). In a disease where telomerase is affected, it does not seem to follow that cancer would be a complication to result. The authors note the paradoxical nature of cancer predisposition in individuals who seem to lack one of the required components for cancer to form. It is thought that without functional telomerase, chromosomes will likely be attached together at their ends through the non-homologous end joining pathway. If this proves to be a common enough occurrence, malignancy even without telomerase present is possible. Myelodysplastic Syndrome is associated with this syndrome usually presenting as a Hypoplastic Bone Marrow that can resemble Aplastic Anemia, but can be differentiated with >10% dysplasia in affected cell lines, sometimes not possible though because of the Hypoplastic marrow reducing blood cells to be observed, genetic clones are usually not present more often than not with Hypoplastic Myelodysplastic Disorder associated with<unk> .
