Definition / general
Clinical features
  • Higher serum acid phosphatase in malaria patients (Indian J Clin Biochem 2011;26:396)
  • Acid phosphatase locus 1 allele:
    • Produced by erythrocytes, encodes low molecular weight phosphotyrosine phosphatase
    • Genetically polymorphic; three common alleles segregating at corresponding locus give rise to six phenotypes (Wikipedia)
    • Associated with systemic lupus erythematosus (Hum Immunol 2012;73:107)
