Short stature and growth failure are common in Bartter’s Syndrome. In subjects with growth hormone deficiency, giving exogenous growth hormone increases the rate of growth and helps subjects attain normal height.
Although now well studied, there is at least one report of low GH levels in a subject with Gitelman’s Syndrome, who was below the 3rd percentile for height, whose growth rate improved 4-fold during growth hormone treatment.
