title: ST-16: a new Bw16 subtype present in Mexican-Americans.
abstract: Using a large battery of Bw16, w38, and w39 antisera, a new variant of Bw16 has been identified in four unrelated Mexican-American families. The serologic pattern obtained is distinct from that for Bw38, Bw39, and 8W57 antigens. Absorption studies confirm the existence of this new Bw16 subtype which we term ST-16. ST-16 is Bw6-associated, with antigen frequency estimated to be 2.5% in Mexican-Americans.
