Identification of G protein alpha subunit mutations in human growth hormone (GH)- and GH/prolactin-secreting pituitary tumors by single-strand conformation polymorphism (SSCP) analysis.

Abstract excerpt

We have applied the polymerase chain reaction (PCR) and single-strand conformation polymorphism analysis (SSCP) to detect activating mutations in the Gs alpha subunit gene, amplifying genomic DNA extracted from growth hormone (GH)- and GH/prolactin (PRL)-secreting human pituitary tumors. Of 15 tumors tested six contained mutations in the analyzed regions of the Gs alpha. SSCP analysis revealed band shift in exon...
