摘要
Background. Recently a locus for antenatal Bartter syndrome associated with sensorineural deafness was mapped to human chromosome 1p31 in a single consanguineous Bedouin family (Brennan ef al. Am J Hum Genet 1998; 62: 355-361). Methods, By haplotype analysis we demonstrate linkage to this locus in nine consanguineous families with antenatal Bartter syndrome associated with sensorineural deafness. Results. The critical interval compatible with linkage was refined to 4.0 cM by two novel recombinational events with markers D1S2661 and D1S475. Conclusion. We thereby confirmed this gene locus and distinguished this clinical subtype from other variants of Bartter syndrome as a new disease entity.
