A new antigen Yk-a (York), and its relationship to Cs-a (Cost).
The antigen Yk-a is detected in 92 and 98% of the American Caucasian and Negro populations, respectively. In population studies with anti-Yk-a and anti-Cs-a, association was demonstrated between the two antigens; however, in two of three informative families Yk-a and Cs-a segregated independently. The possibility that these antigens have a relationship with leucocyte antigens is discussed.
