We describe 19 males with Aarskog syndrome who were treated with growth hor
mone (GH) and enrolled in the National Cooperative Growth Study (NCGS), The
re was a significant increase in both growth rate (3.9+/-1.9 cm/yr vs 8.9+/
-1.7 cm/yr, p<0.001) and height SD score (change in HtSDS=1.0+/-0.8). The i
ncrease in HtSDS was dependent on treatment duration, frequency of injectio
ns, weight-for-height SDS, and HtSDS at enrollment. The results of our stud
y suggest a positive effect of GH treatment on growth and adult height in A
arskog syndrome patients.
