Short Stature Due To Primary Acid-labile Subunit Deficiency

Description

Short stature due to primary acid-labile subunit (ALS) deficiency is characterized by moderate postnatal growth deficit, markedly low circulating levels of insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 3 (IGFBP-3), and hyperinsulinemia, in the absence of growth hormone (GH) deficiency or GH insensitivity.
