Deficiencia selectiva familiar de somatotrofina

Four distinct types of isolated growth hormone deficiency (IGHD) have been described to date. Of these IGHD type II has been defined as having a dominant mode of inheritance. We performed a molecular genetic analysis of two patients clinically characterized as IGHD type II. One of the patients and her father shared a heterozygous G-A transition in the first 5' donor splice site of intron III. The second father and daughter studied also showed a heterozygous G-A transition in the fifth base from the 5' donor splice site in the same intron. Both mutations altered the correct splicing of the growth hormone pre-mRNA when the corresponding genes were expressed in COS-7 cells. We propose that both inherited mutations are responsible for IGHD type II in these patients.
