TLDR Vitamin D Dependent Rickets Type-2A can cause complete hair loss and bone growth issues in infants.
Vitamin D Dependent Rickets Type-2A (VDDR-2A) is a rare condition that manifests as refractory rickets and growth retardation within the first year of life. It is often associated with alopecia totalis, a condition characterized by complete hair loss on the scalp. Rickets, a disease affecting growing bones due to unmineralized matrix at the growth plates, can be caused by various factors, including vitamin D disorders, calcium and phosphorus deficiencies, and distal renal tubular acidosis.
