- HLA-B52
Alleles
There are 18 alleles, with 14 amino acid sequence variants in B52. Of these only 9 are frequent enough to have been reliably serotyped. B*5201 is the most common, but others have a large regional abundance.{|border="0" cellspacing="0" cellpadding="1" align="left" style="text-align:center; margin-right: 3em; border:1px #ffeebb solid; background:#f8f6f8; "
