Genetics Home Reference : ²⁵ Osteoporosis-pseudoglioma syndrome is a rare condition characterized by severe thinning of the bones (osteoporosis) and eye abnormalities that lead to vision loss. In people with this condition, osteoporosis is usually recognized in early childhood. It is caused by a shortage of minerals, such as calcium, in bones (decreased bone mineral density), which makes the bones brittle and prone to fracture. Affected individuals often have multiple bone fractures, including in the bones that form the spine (vertebrae). Multiple fractures can cause collapse of the affected vertebrae (compressed vertebrae), abnormal side-to-side curvature of the spine (scoliosis), short stature, and limb deformities. Decreased bone mineral density can also cause softening or thinning of the skull (craniotabes).

MalaCards based summary : Osteoporosis-Pseudoglioma Syndrome, also known as oppg, is related to persistent hyperplastic primary vitreous and exudative vitreoretinopathy. An important gene associated with Osteoporosis-Pseudoglioma Syndrome is LRP5 (LDL Receptor Related Protein 5), and among its related pathways/superpathways are Wnt signaling pathway and Signaling by Wnt. The drugs Lithium carbonate and Citric Acid have been mentioned in the context of this disorder. Affiliated tissues include bone, eye and heart, and related phenotypes are muscular hypotonia and cataract

Disease Ontology : ¹² An autosomal recessive disease characterized by congenital or infancy-onset blindness, very low bone mass, decreased trabecular bone volume, severe juvenile-onset osteoporosis and spontaneous fractures, pseudoglioma, microphthalmia that has material basis in homozygous or compound heterozygous mutation in the LRP5 gene on chromosome 11q13.
