title: Additions to the exclusion map of man.
abstract: Exclusion mapping was applied to individuals with monosomic segments defined by chromosomal banding. A range of genetic markers and blood groups was determined resulting in new exclusions for unassigned markers at the following segments : (3)(p25 leads to pter) - JK, GPT, PI ; (4)(127 leads to 31) - MNS, JK, PI, C3, F13A, F13B ; (7))q22) - LU, F13A ; (12)(p12) - MNS ; (12)(p13) and (15)(q15) - GPT, C3 ; (12) (pter) and (19)(p or qter) - MNS, GPT, PI ; and (18)(q21 leads to 23) - MNS, JK, F13A. These exclusions may be useful for narrowing the regional localisations of any genetic markers subsequently assigned to the chromosome involved in the exclusion. No new gene assignments were made from cases where family data was available.
