Enzymatic function assays were carried out to detect the Kell glycoprotein on RBCs. The <jats:italic>KEL<\/jats:italic> genes were sequenced to detect genetic variation. To determine the origin of this novel allele, family studies were conducted.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The alloantibody was identified as anti\u2010Ku. The donor was typed K<jats:sub>0<\/jats:sub>. The <jats:italic>KEL<\/jats:italic> gene\u2010sequencing data revealed that this K<jats:sub>0<\/jats:sub> donor is a compound heterozygote with two different null alleles. He bears a novel 730delG mutation in one allele. Family studies suggested that the donor inherited the 730delG mutation from his father. The endothelin\u2010converting activity assay indicated that his RBCs had no functional Kell glycoprotein. Other family members who had only one null allele with the 730delG mutation had the phenotype (K\u2212, k+).<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> For blood transfusion safety, it is important to establish an effective screening algorithm to identify rare phenotypes, such as the K<jats:sub>0<\/jats:sub> phenotype, and to establish a database of rare blood groups.<\/jats:p>","DOI":"10.1111\/j.1365-3148.2011.01084.x","type":"journal-article","created":{"date-parts":[[2011,6,30]],"date-time":"2011-06-30T11:09:56Z","timestamp":1309432196000},"page":"318-324","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Genetic and functional analyses describe a novel 730delG mutation in the <i>KEL<\/i> gene causing K<sub>0<\/sub> phenotype in a Taiwanese blood donor"],"prefix":"10.1111","volume":"21","author":[{"given":"M.\u2010H.","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.\u2010F.","family":"Kuo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.\u2010S.","family":"Hung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.\u2010C.","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.\u2010S.","family":"Hung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.\u2010J.
