The products of expression of the hGH gene family share 95% of homology among them. The main GH form corresponds to the 22 kDa GH-N, expressed not only at the pituitary level but also in many different peripheral cells and tissues. About 10% of pituitary GH-N transcripts suffer a physiological postranscriptional modification, occurred by alternative splicing of exon III, giving origin to a 20 kDa variant. Among placental GH genes, the most important seems to be the GH-V, which differs from 22 kDa GH-N in only eight amino acids.
