Variant position:  281

Type of variant:  Polymorphism

Residue change:  From Valine (V) to Isoleucine (I) at position 281 (V281I, p.Val281Ile).

Physico-chemical properties:  Similar physico-chemical property. Both residues are medium size and hydrophobic.

BLOSUM score:  3

Polymorphism:  Three alleles are known: AADAC*1, AADAC*2 and AADAC*3. The sequence shown is that of AADAC*1 which is found in European American, African American, Japanese and Korean populations at allelic frequencies of 39.3 to 47.4%. The AADAC*2 allele is found in European American, African American, Korean, and Japanese populations at allelic frequencies of 52.6 to 63.5% whereas the AADAC*3 allele is found in European American (1.3%) and African American (2.0%) samples but not in Japanese or Korean samples.

Variant description:  In alleles AADAC*2 and AADAC*3; mildly decreased enzyme activity.
