NCIt definition : Human DKC1 wild-type allele is located in the vicinity of Xq28 and is approximately
15 kb in length. This allele, which encodes H/ACA ribonucleoprotein complex subunit
4 protein, plays a role in the stabilization and maintenance of telomerase and H/ACA
small nucleolar RNA ribonucleoprotein biogenesis. Mutation of the gene is associated
with both Hoyeraal-Hreidarsson syndrome and X-linked dyskeratosis congenita.;
