Gilles de la Tourette syndrome is a heritable neuropsychiatric disorder. In order to determine the chromosomal localisation of the locus involved, genetic linkage studies were initiated in six extended families. The Gilles de la Tourette gene has been tentatively assigned to chromosome 18q22.1. In our present study no evidence for genetic linkage on chromosome 18 and chromosome 7 was obtained. Data from the markers tested made it possible to exclude the whole of chromosome 18 and the chromosome 7q21.3-qter region as a site for the Gilles de la Tourette gene.
抽动秽语综合征是一种遗传性神经精神障碍。为了确定相关基因座的染色体定位,我们在六个大家庭中开展了遗传连锁研究。抽动秽语基因已初步定位到18号染色体q22.1区域。在我们目前的研究中,未获得18号染色体和7号染色体存在遗传连锁的证据。所检测标记的数据使我们能够排除整个18号染色体以及7号染色体q21.3 - qter区域作为抽动秽语基因的位点。
