HLA Database » Allele Report

The list below shows all populations in AFND that contains the allele. If an allele has an entry with a lower resolution this will be shown at the end.

Allele: 

B*18:26
Allele reported 9 time(s) and present in 6 population(s).

Notes:

* Allele Frequency: Total number of copies of the allele in the population sample (Alleles / 2n) in decimal format.
   Important: This field has been expanded to four decimals to better represent frequencies of large datasets (e.g. where sample size > 1000 individuals)
* Phenotype Frequency: Percentage of individuals who have the allele or gene (Individuals / n).
* Allele Frequencies shown in green were calculated from Phenotype Frequencies assuming Hardy-Weinberg proportions.
