High resolution mapping and mutation analyses of candidate genes in the urofacial syndrome (UFS) critical region.
The urofacial (Ochoa) syndrome (UFS) characterized by congenital obstructive uropathy and abnormal facial expression is a rare disorder caused by a single recessive disease gene. Our previous studies using homozygosity mapping have located the UFS gene to a genomic interval of approximately 360 kb on chromosome 10q23-10q24. In this study, we have constructed a genomic sequence map covering the entire UFS interval and narrowed the disease interval to a genomic region of 220 kb that harbor the newly identified ACDP1 gene in addition to part of the GOT1 gene which has already been excluded as a candidate for UFS. Extensive search for mutations in the coding region, the 5' and 3' untranslated regions, the promoter region, and the exon/intron junctions failed to identify a pathogenic mutation in UFS patients. Furthermore, our analyses indicated that the same gene on chromosome 10q is responsible for all UFS patients from multiple ethnic groups.
