      Using inverse polymerase chain reaction (PCR), we have cloned partial intronic sequences from human glutamic acid decarboxylase (GAD) gene. A small 153 bp core region was selected from the GAD cDNA sequence to design outward primers corresponding to its 3′ and 5′ ends. EcoRI digested human DNA which had been circularized by self-ligation and then linearized withSacII was used as a substrate to can.y out PCR. This gave a 900 bp long product which was cloned into pUC19. The sequence analysis of this fragment revealed the presence of introns in the region flanking the selected core DNA. In this work we used this technique to walk into the upsteam region of the GAD gene using sequence information from its cloned cDNA.
