| Popis: | We have established rBAT (named as SLC3A1 in the Genome Data Base) as a gene responsible for cystinuria, a heritable disorder of amino acid transport. The cystinuria locus has been mapped by linkage between microsatellite markers D2S119 and D2S177. Fluorescence in situ hybridization (FISH) either with Alu-polymerase-chain-reaction (PCR)-amplified sequences of a yeast artificial chromosome (YAC) containing the rBAT gene or with rBAT-specific PCR-amplified genomic fragments, and chromosome G-banding have cytogenetically mapped rBAT to 2p16.3. In order to correlate the physical and genetic information on cystinuria, we have performed FISH with combinations of Alu-PCR-amplified sequences from YACs containing rBAT or the D2S119 and D2S177 loci. In all cases, a fused signal is obtained that demonstrates their close physical location; this allows the assignment of rBAT, cystinuria and their linked markers, D2S119 and D2S177, to 2p16. |
