Shared data
Locus Locus (genetics) In the fields of genetics and genetic computation, a locus is the specific location of a gene or DNA sequence on a chromosome. A variant of the DNA sequence at a given locus is called an allele. The ordered list of loci known for a particular genome is called a genetic map...	chr.6 Chromosome 6 (human) Chromosome 6 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 6 spans more than 170 million base pairs and represents between 5.5 and 6% of the total DNA in cells...  6p21.31

HLA-DR13(DR13) is a HLA

Human leukocyte antigen

The human leukocyte antigen system is the name of the major histocompatibility complex in humans. The super locus contains a large number of genes related to immune system function in humans. This group of genes resides on chromosome 6, and encodes cell-surface antigen-presenting proteins and...

HLA-DR6

HLA-DR6 is a broad-antigen serotype that is further split into HLA-DR13 and HLA-DR14 antigen serotypes.-Serology:DR6 serological reactivity is relatively poor compared to other serological tests for DR antigens. Compare to DQ2 or DR7....

Disease associations

DRB1*1302 is linked to early childhood myastenia gravis. Alleles of DR13 along with immunization for hepatitis B and C are most protective against the disease.

HLA-DR13 is genetically linked to DR52 and HLA-DQ6

HLA-DQ6

HLA-DQ6 is a human leukocyte antigen serotype within HLA-DQ  serotype group. The serotype is determined by the antibody recognition of β6 subset of DQ β-chains. The β-chain of DQ isoforms are encoded by HLA-DQB1 locus and DQ6 are encoded by the HLA-DQB1*06 allele group. This group currently...

HLA-DQ1

HLA-DQ1 is a serotype that covers a broad range of HLA-DQ haplotypes. Historically it was identified as a DR-like alpha chain called DC1, later, it was among 3 types DQw1 , DQw2 and DQw3. Of these three serotyping specificities only DQw1 recognized DQ alpha chain. The serotype is positive in...
