Abstract
Unlabelled:
We report a 1-year-old Japanese boy and his father with isolated growth hormone deficiency II. In both cases, a G-->A transition of the first base of the donor splice site of intron 3 of the growth hormone-1 gene was detected. All unaffected family members were homozygous normal.
Conclusion:
This is the fourth reported case of autosomal isolated growth hormone deficiency II with a G-->A transition. The CG dinucleotide at the exon 3-intron 3 junction of the growth hormone-1 gene appears to be a hot spot for point mutations.
