title: The HLA-A*68:23 allele in the Chilean population.
abstract: HLA-A*68:23, first described in 2002, has not been widely reported. The studies reported here were performed for support of a collaborative hematopoietic stem cell transplantation program at Luis Calvo Mackenna Hospital for which St. Jude Children's Research Hospital provided human leukocyte antigen (HLA) typing. Family studies performed between 2000 and 2011 included 197 patients and their immediate family members. In a total of 559 individuals, A*68:23 was confirmed by DNA sequencing in eight individuals with no known relationship to each other. A*68:23 positive individuals included six patients, along with one of their parents, and two parents whose children did not inherit A*68:23. The frequency of A*68:23 in this Chilean population is >0.0125. This HLA-A allele appears to fit the description of a well-documented allele in this population studied in Santiago, Chile.
