+== Disease ==
+[[http://www.uniprot.org/uniprot/USB1_HUMAN USB1_HUMAN]] Dyskeratosis congenita;Poikiloderma with neutropenia. Poikiloderma with neutropenia (PN) [MIM:[http://omim.org/entry/604173 604173]]: A genodermatosis characterized by poikiloderma, pachyonychia and chronic neutropenia. The disorder starts as a papular erythematous rash on the limbs during the first year of life. It gradually spreads centripetally and, as the papular rash resolves, hypo- and hyperpigmentation result, with development of telangiectasias. Another skin manifestation is pachyonychia, but alopecia and leukoplakia are distinctively absent. Patients have recurrent pneumonias that usually result in reactive airway disease and/or chronic cough. One of the most important extracutaneous symptoms is an increased susceptibility to infections, mainly affecting the respiratory system, primarily due to a chronic neutropenia and to neutrophil functional defects. Bone marrow abnormalities account for neutropenia and may evolve into myelodysplasia associated with the risk of leukemic transformation. Poikiloderma with neutropenia shows phenotypic overlap with Rothmund-Thomson syndrome. Note=The disease is caused by mutations affecting the gene represented in this entry.<ref>PMID:20004881</ref> <ref>PMID:20503306</ref>
+== Function ==
+[[http://www.uniprot.org/uniprot/USB1_HUMAN USB1_HUMAN]] Phosphodiesterase responsible for the U6 snRNA 3' end processing. Acts as an exoribonuclease (RNase) responsible for trimming the poly(U) tract of the last nucleotides in the pre-U6 snRNA molecule, leading to the formation of mature U6 snRNA 3' end-terminated with a 2',3'-cyclic phosphate.<ref>PMID:22899009</ref> <ref>PMID:23190533</ref>
