The gene coding for the transacylase subunit (DBT) of the human branched-chain keto acid dehydrogenase complex was localized to chromosome 1 by probing panels of human x mouse chromosome hybrids with an E2 cDNA amplified by the polymerase chain reaction. Additional data with two hybrids containing chromosome 1 fragments suggest that the DBT gene is located on the short arm (1pter----p21) of the chromosome.
通过用聚合酶链反应扩增的E2 cDNA探测人x小鼠染色体杂种板，将人类支链酮酸脱氢酶复合体转酰酶亚基（DBT）的编码基因定位到1号染色体上。对两个含有1号染色体片段的杂种的进一步数据表明，DBT基因位于该染色体的短臂（1pter----p21）上。
