A rare genetic disease characterized by congenital contractures of the distal interphalangeal joints, progressive stiffness of the shoulders and neck, keloid scarring, increased optic cup-to-disc ratio, and renal stones. Additional reported features include arthritis, osteoporosis, hypoplastic flexion creases, clinodactyly, anxiety, and facial dysmorphism (such as sloping forehead, prominent supraorbital ridges, downslanting palpebral fissures, prominent ears, and high arched palate). Female carriers exhibit a variable, milder phenotype.	Interprets	True	Optic cup/disc ratio	Inferred relationship	Some	6
A condition where there is a noticeable difference in the cupping (or indentation) of the optic disc between the two eyes which may indicate glaucomatous optic nerve damage in the eye with the larger cup-to-disc ratio.	Interprets	True	Optic cup/disc ratio	Inferred relationship	Some	2
