Adequate protein intake to maintain the growth of preterm infants cannot be provided by standard fortification methods because of variation in the protein content of human milk. Individualization is necessary to achieve target protein intakes.

Background/aim: The exon 3-deleted/full-length (d3/fl) growth hormone (GH) receptor (GHR) polymorphism has been associated with responsiveness to GH therapy in some diagnostic groups. However, there are still controversies on this issue. To evaluate the effect of the GHR exon 3 polymorphism on growth after 1 and 2 years of GH therapy in Turkish patients with GH deficiency (GHD) and Turner's syndrome (TS) and the distribution of GHR exon 3 isoforms.
