Familial isolated growth hormone deficiency (IGHD) type IA is characterized by a complete absence of human growth hormone (hGH) resulting in most cases from either a 6.7 or 7.7 kb deletion of DNA containing the hGH-1 gene.
These data are important for prenatal diagnosis of at-risk pregnancies and for families at risk for recurrence and underline clearly the fact that the hGH-I gene deletion represents a common cause for growth hormone deficiency associated with severe growth retardation (height less than -4.5 SD score).
The peptides were designated from the N-terminus sequences of the hormone positions at 1-15 (hGH(1-15); H2N-Phe1-Pro2-Thr3-Ile4-Pro5-Leu6-Ser7-Arg8-L eu9-Phe10-Asp11-Asn12-Ala13-Met14-Leu15 -COOH), 6-13 (hGH(6-13)), 7-13 (hGH(7-13)) and 8-13 (hGH(8-13)), which enhanced insulin-producing hypoglycemia.

We report on a girl suffering from CF and short stature in whom DNA analysis using polymerase chain reaction and Southern blot techniques of the human growth hormone (hGH) gene cluster revealed a 6.7-kb gene deletion encompassing the hGH-1 gene.
