Zusammenfassung:A detection method for detecting a variation in iGHI effective to act as an indicator of GH dysfunction in an individual, comprises the steps of comparing a test sample comprising a nucleotide sequence of the human GHI gene from the individual with a standard sequence known to be that of the human GHI gene. A difference between the test sample sequence and the standard sequence indicates the presence of a variation effective to act as an indicator of GH dysfunction (hereinafter''variant of GHI''). The test sample is obtained from a individual exhibiting the following criterion: (i) growth failure, defines as a growth pattern [delineated by a series of height measurements; Brook CDG (Ed) Clinical Paediatric Endocrinology 3rd Ed, Chapter 9, p141 (1995, Blackwell Science)] which, when plotted on a standard height chart [Tanneret al Arch Dis Child 45 755-762 (1970)], predicts an adult height for the individual which is outside the individual's estimated target adult height range, the estimate being based upon the heights of the individual's parents. Also disclosed are mutations thereby detected, and their use in screening patients for growth hormone irregularities or for producing variant proteins suitable for treating such irregularities.
