Molecular characterization of an intragenic minisatellite (VNTR) polymorphism in the human parathyroid hormone-related peptide gene in chromosome region 12p12.1-p11.2.
The human parathyroid hormone-related peptide (hPTHrP) gene in chromosome region 12p12.1-p11.2 plays an important role in mammalian development and specifically in skeletogenesis. We have characterized a VNTR polymorphism in the hPTHrP gene that is located in an intron 100-bp downstream of exon VI that encodes a 3' untranslated region. By PCR analysis eight different alleles were identified in a group of 112 unrelated individuals. All eight alleles were sequenced and the repeat unit was identified as the general sequence [G(TA)nC]N, where n = 4 to 11 and N = 3 to 17. This polymorphic sequence-tagged site will be useful for mapping chromosome 12p and will aid in testing for linkage of genetic diseases to the hPTHrP gene.
