The Human Leukocyte Antigen (HLA) gene complex on human chromosome 6 is one of the most polymorphic regions in the human genome, and contributes in large part to the diversity of the immune system. Accurate typing of HLA genes with short read sequencing data has historically been difficult due to the sequence similarity between the polymorphic alleles. xHLA iteratively refines the mapping results at the amino acid level to achieve 99 to 100% 4-digit typing accuracy for both class I and II HLA genes, taking only about 3 minutes to process a 30X whole genome BAM file on a desktop computer.
Simply pull from Docker hub:
docker pull humanlongevity/hlaOr, compile docker image yourself:
cd docker
make build
make deployRun xHLA caller directly on an indexed BAM file generated using BWA-mem against hg38 reference without alt contigs:
docker run -v `pwd`:`pwd` -w `pwd` humanlongevity/hla \
--sample_id test --input_bam_path tests/test.bam \
--output_path testFor other types of BAMs, pre-processing is required. Please check details here.
Output is a JSON file that lists 12 HLA alleles, 2 for each of the HLA genes:
