Linkage localization of the thoraco-abdominal syndrome (TAS) gene to Xq25-26.
The thoraco-abdominal syndrome (TAS) presents a closure defect confined to the ventral midline, manifested as ventral hernia of various degrees in all affected individuals and antero-lateral diaphragmatic defect manifested almost exclusively in affected males. The syndrome is inherited as an X-linked dominant trait affecting blastogenesis (XLB mutation). We studied 27 members of the TAS family for linkage on the X chromosome. The best lod score of 5.5 at theta 0.04 was found for the HPRT locus on Xq26.1. A multilocus lod score of 12.4 was observed when the linkage analysis utilized additional markers in Xq25-26.
