Pseudohypoparathyroidism type 1A (PHP1A/iPPSD2) is characterized by brachydactyly, short stature, round face, stocky appearance, ectopic calcifications (Albright hereditary osteodystrophy [AHO]), developmental delay, and resistance to PTH or other hormones binding G-protein coupled receptors (GPCR) (1). Here, PTH is linked to Global developmental delay.
