Vitamin D dependent rickets

Vitamin D dependent rickets refers to a group of rare, inherited metabolic bone disorders characterized by severe defects in vitamin D activation or end-organ responsiveness, primarily manifesting in infants and young children The condition disrupts normal mineral homeostasis and skeletal mineralization, leading to hallmark features such as softening of the bones, bowed legs, metaphysical widening, growth delay, hypotonia, and dental anomalies
