Background. Autosomal-dominant medullary cystic kidney disease type 1 (MCKD1) is a tubulointerstitial nephropathy that causes renal salt wasting and end-stage renal failure in the sixth decade of life. The chromosomal locus for MCKD1 was localized to chromosome 1q21 in a Cyprotic kindred. In this report we describe further refinement of the critical genetic region by a recombination in a Belgian kindred. Methods. Clinical data and blood samples of 33 individuals from a large Belgian kindred were collected and high-resolution haplotype analysis was performed. Results. In the Belgian kindred linkage to the MCKD1 locus on chromosme 1q21 was found with a logarithm of odds (LOD) score significant for linkage. A recombination in individual III:7 for marker D1S2624 refines the critical genetic region to 2.1 Mb. In this kindred a wide variety of clincial symptoms and age of onset of renal failure was detected. Conclusion. We confirm the MCKD1 locus on chromosome 1q21 and show further refinement of the MCKD1 locus to 2.1 Mb. This allowed us to exclude another 17 genes as positional candidate genes.
