Abstract

Urofacial (Ochoa) syndrome is an autosomal recessive disease characterized by distorted facial expression and urinary abnormalities. Previously, we mapped the UFS gene to chromosome 10q23-q24 and narrowed the interval to one YAC clone of 1410 kb. Here, we have constructed a BAC/PAC contig of the 1-Mb region using STS content mapping with 42 BAC/PAC-end sequences, 9 previously reported and 16 newly identified microsatellite markers, and 14 EST markers. A total of 26 polymorphic microsatellite markers were genotyped for 31 UFS patients from Colombia and 2 patients from the United States. Haplotype analyses suggest that the UFS gene is located within two overlapping BAC clones, a region of <360 kb of DNA sequence. We tested 42 EST markers previously mapped to the D10S1709-D10S603 interval against the BAC/PAC contig and identified 11 ESTs located in the 1-Mb region. Four of the 11 ESTs mapped to the 360-kb UFS critical region. Shotgun sequencing of the two BAC clones and BLASTN search of the E ST databases revealed 3 other ESTs contained in the UFS critical region. These results will facilitate the cloning and identification of the UFS gene.
