<qa>  What is the reason for the GH treatment?Additionally, we completed a study in which we treated children with PHP1a who are not GH deficient i.e., GH sufficient. The rationale is that GH treatment could maximize linear growth velocity prior to the premature bone fusion that occurs in this condition and potentially improve final adult height. The supply of growth hormone has ended for this study, and we are following those participants who were in this study and received the growth hormone supply. Some of these patients remain on growth hormone as per clinical care secondary to their responses.
