Tools for building, analyzing and evaluating HLA haplotypes from families.

The highly polymorphic classical human leukocyte antigen (HLA) genes display strong linkage disequilibrium (LD) that results in conserved multi-locus haplotypes. For unrelated individuals in defined populations, HLA haplotype frequencies can be estimated using the expectation-maximization (EM) method. Haplotypes can also be constructed using HLA allele segregation from nuclear families.

Stem Cell Transplantation and Informatics: Current Considerations.

Informatics strategies and applications available to stem cell transplant (SCT) programs are diverse and changing rapidly. Although most hospitals have electronic medical records (EMRs), few are equipped with specialized SCT applications. Most EMRs do not contain critical elements to support SCT practice and research.

HLA Haplotype Validator for quality assessments of HLA typing.

HLA alleles are observed in specific haplotypes, due to Linkage Disequilibrium (LD) between particular alleles. Haplotype frequencies for alleles in strong LD have been established for specific ethnic groups and racial categories. Application of high-resolution HLA typing using Next Generation Sequencing (NGS) is becoming a common practice in research and clinical laboratory settings.
