The Colton blood group locus. A linkage analysis.
Accumulated family information was compiled in an attempt to verify the chromosomal location of the Colton blood group locus (CO). Two-point linkage analysis of CO and 46 other polymorphic loci excludes CO from 1p36 to 1q23, 3q21 to 3q26, 4q13 to 4q28, 6p24 to 6 cen, and 19p13.2 to 19 cen and from linkage groups bounded by ABO and ORM, PI and IGHG, and HP and GOT2. The dwindling odds of linkage between CO:JK are reinforced (z = -5.28 at theta = 0.20). Close linkage of CO with ACP1 and D2S5 could not be demonstrated. The proposed chromosome 2 location of CO is therefore questioned.
