title: Isolation of sequences from Xp22.3 and deletion mapping using sex chromosome rearrangements from human X-Y interchange sex reversals.
abstract: A repeated DNA element (STIR) interspersed in Xp22.3 and on the Y chromosome has been used as a tag to isolate seven single-copy probes from the human sex chromosomes. The seven probes detect X-specific loci located in Xp22.3. Using a panel of X-chromosomal deletions from X-Y interchange sex reversals (XX males and XY females), these X-specific loci and some additional ones were mapped to four contiguous intervals of Xp22.3, proximal to the pseudoautosomal region and distal to STS. The construction of this deletion map of the terminal part of the human X chromosome can serve as a starting point for a long-range physical map of Xp22.3 and for a more accurate mapping of genetic diseases located in Xp22.3.
