AARSKOG-SCOTT SYNDROME - CONFIRMATION OF LINKAGE TO THE PERICENTROMERIC REGION OF THE X-CHROMOSOME

Aarskog-Scott syndrome was tentatively mapped to Xq13 on the basis of an X:8 translocation by Bawle et al. [Am J Med Genet 17:595-602, 1984] . A review of the cytogenetics and the use of molecular markers in tha t family have resulted in revision of the breakpoints of the transloca tion to Xp 11.2 and 8q11.21 [Glover et al., Hum Mol Genet 2:1717-1718, 1993]. Two families, including one of the two initial families with A arskog-Scott syndrome [Scott, BD:OAS VII (6): 240-246, 1971], have par ticipated in our study to evaluate the localization of the gene for Aa rskog-Scott syndrome to the pericentromeric region of the X chromosome . Using a series of DNA probes, we have been able to confirm linkage t o the X chromosome, with multipoint analysis indicating the most likel y localization of the gene to be on the proximal short arm.
