title: Organization of the human natriuretic peptide receptor A gene.
abstract: We have determined the structural organization of the human natriuretic peptide receptor A (hNPRA) gene without screening the genomic library. Based on the information for the cDNA of hNPRA, we amplified some fragments of the long polymerase chain reaction (PCR) products covering all genomic sequences of the gene and directly sequenced the products after extraction and purification. The hNPRA gene spans approximately 16 kb and contains 22 exons and 21 introns. All of the exon-intron junction sequences coincide with the GT/AG consensus sequence. The sequence encoding the transmembrane domain, one part of the hNPRA topological structure, exists in exon 7. The results of this first study, determination of the hNPRA gene structure, will facilitate further genetic analysis of the hNPRA gene and its related diseases.
