Living with Kenny-Caffey syndrome

A rare bone condition with short stature, thick long bones, low calcium from a low-working parathyroid gland, and facial and eye differences.

Understanding Kenny-Caffey syndrome

Kenny-Caffey syndrome is a rare bone condition with slow growth, short height, and low calcium.

Features include dense, narrow long bones, a late-closing soft spot on the skull, low calcium from underactive parathyroid glands, and facial differences such as a prominent forehead, small eyes, and a small jaw. Eye and dental differences are also listed. The recessive form is more severe, with slower growth, small hands and feet, a small head, intellectual disability, and repeated bacterial infections. It is noticed in childhood.
