| Abstract: | The gene locus for cystinosis has been mapped between markers D17S1583 and D17S1584 on the short arm of chromosome 17. Using markers encompassing the cystinosis region, we assigned different yeast artificial chromosome (YAC) clones previously identified by sequence tagged site (STS) screening to 17p13.3. Three of the clones hybridized to the target 17p gene region; one of these was chimeric, hybridizing both to chromosomes 3p and 5q; two of the YACs did not contain sequences of 17p13.3. Our physical mapping has identified candidate YACs as a first step towards a positional cloning approach. Received: 28 February 1996 / Revised: 3 May 1996 |
