Establishing multiple omics baselines for three Southeast Asian populations in the Singapore Integrative Omics Study.

The Singapore Integrative Omics Study provides valuable insights on establishing population reference measurement in 364 Chinese, Malay, and Indian individuals. These measurements include > 2.5 millions genetic variants, 21,649 transcripts expression, 282 lipid species quantification, and 284 clinical, lifestyle, and dietary variables.

Predicting HLA alleles from high-resolution SNP data in three Southeast Asian populations.

The major histocompatibility complex (MHC) containing the classical human leukocyte antigen (HLA) Class I and Class II genes is among the most polymorphic and diverse regions in the human genome. Despite the clinical importance of identifying the HLA types, very few databases jointly characterize densely genotyped single nucleotide polymorphisms (SNPs) and HLA alleles in the same samples. To date, the HapMap presents the only public resource that provides a SNP reference panel for predicting HLA alleles, constructed with four collections of individuals of north-western European, northern Han Chinese, cosmopolitan Japanese and Yoruba Nigerian ancestry.

Identification of a novel DPA1 allele, DPA1*010602, in an East African population.

We report here a novel DPA1 allele, DPA1*010602, which was identified from an East African population during sequence-based human leukocyte antigen DPA1 typing. Through cloning and sequencing of multiple clones we confirmed that the new allele is identical to DPA1*010301 at exon 2 with the exception of two nucleotide substitutions (ATG to CAG) at codon 31. The substitutions changed the amino acid at codon 31 from methionine to glutamine.
