GT repeat polymorphism in the 5' flanking region of the human growth hormone receptor gene.
A polymorphic GT dinucleotide repeat sequence has been identified in the 5' flanking region of the human growth hormone receptor (hGHR) gene on chromosome 5p13.1-p12, within the promoter region of the V9 5'UTR exon. Thirteen alleles have been identified in 50 non-related individuals, with an observed heterozygosity of 52%. The major allele contains 24 repeats, although a range of 19-32 repeats has been observed. Codominant segregation was demonstrated in five two-generation and two three-generation families. This marker may be useful in analysing the role of the hGHR gene in pre- and postnatal growth disorders.
