Novel human leukocyte antigen class I and class II alleles identified by sequence-based typing in the Genetics of Kidneys in Diabetes (GoKinD) study population.

Nine novel HLA class I and class II alleles were identified by sequence-based typing (SBT) in Caucasian participants from the Genetics of Kidneys in Diabetes (GoKinD) study. All novel alleles were single nucleotide substitutions. Seven alleles resulted in an amino acid change and two alleles were silent substitutions.

Identification of two novel DQA1 alleles, DQA1*0107 and DQA1*0602, by sequence-based typing in the GoKinD population.

Two novel DQA1 alleles, DQA1*0107 and DQA1*0602, were discovered using DQA1 sequence-based typing (SBT) in participants in the Genetics of Kidneys in Diabetes (GoKinD) Study. The DQA1*0107 allele, found in three unrelated Caucasian participants, contains a novel polymorphism at codon 79 of exon 2 (CGC-->TGC), which results in an amino acid change from an arginine to a cysteine. The participants containing this novel polymorphism also had a 1-bp insertion in intron 2 that is common to the *01 alleles.
