Abstract

The human Deltex (DTX1) gene encodes a cytoplasmic protein that functions as a positive regulator of the Notch signaling pathway. We have determined the genomic organization and map location of the human gene. DTX1 encodes a 2.5-kb cDNA that is composed of nine exons. The DTX1 gene maps to chromosomal region 12q24 in the vicinity of the Noonan syndrome critical region. We have fine-mapped DTX1 to within this critical region and evaluate it as a candidate gene for this disorder.
