The Infinium Asian Screening Array (ASA) combines genome-wide coverage of East Asian populations, relevant clinical research content, and scalability to deliver a powerful, cost-effective tool for genomic screening.
The array was built using an East Asian reference panel containing 9000 whole-genome sequences. It includes coverage of populations underrepresented in the 1000 Genomes Project.
The Infinium Asian Screening Array builds on the success of the Infinium Global Screening Array, which was developed by a community of researchers, healthcare networks, direct to consumer companies, and service providers. Illumina screening arrays have been widely adopted, with over 20 million samples ordered by a global community of users.
The array provides a genomic tool for disease risk profiling, pharmacogenomics research, wellness and lifestyle reporting, and complex disease research. It includes updated markers from clinical databases, including ClinVar and PharmGKB.
Predesigned booster content is available as an add-on to the array.
The array supports genotyping and CNV calling for several sample types, including saliva, blood, buccal swabs, and formalin-fixed, paraffin-embedded (FFPE) samples. The Infinium platform is trusted for excellent data quality, with call rates > 99% and reproducibility > 99.9%. The high-throughput Infinium workflow maximizes sample processing while minimizing costs, instrumentation, lab space, and hands-on time.
