The clinical and biochemical characteristics of ARHR2 closely resemble X‐linked hypophosphatemia (XLH) and other genetic forms of rickets, including short stature, bone deformities and pain, gait abnormalities, renal phosphate wasting, and elevated FGF23 (Haffner et al., 2019; Levy‐Litan et al., 2010). Here, ENPP1 is linked to rickets.
