Turkish
We present three novel homozygous LRP5 mutations found in 3 unrelated Turkish children with consanguineous parents, along with clinical phenotypes and response to treatment with bisphosphonates (bisP). [ncbi.nlm.nih.gov]
Conclusion: We report three novel LRP5 mutations in 3 Turkish patients with OPPG. [karger.com]
The mutation was present in the heterozygous state in the patients’ parents and was absent on 100 chromosomes from healthy Turkish controls. [nature.com]

Collapse
METHODS: Three children (ages 9 to 11 years) with osteoporosis pseudoglioma syndrome who had multiple vertebral collapse were treated over a 2-year period with intermittent intravenous bisphosphonate infusions (pamidronate in 2, clodronate in 1). [ncbi.nlm.nih.gov]
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. [ghr.nlm.nih.gov]

Visual Impairment

Most patients with OPPG are blind by 15 years of age; however, this patient’s visual impairment only caused mild functional compromise. [bone-abstracts.org]
We sequenced the coding exons of LRP5 in 37 probands suspected of having OPPG on the basis of the co-occurrence of severe congenital or childhood-onset visual impairment with bone fragility or osteoporosis recognized by young adulthood. [unboundmedicine.com]

Treatment
We conclude that early detection of LRP5 mutations is important for initiation of treatment of reduced bone density in the patients and their carrier relatives. [ncbi.nlm.nih.gov]

Treatment: Bisphosphonate treatment can improve bone density, and should be started early. The importance of trauma avoidance should be emphasized for all patients. Vitamin D insufficiency should be treated. [wohproject.org]
Prognosis
Early identification of the underlying cause and its genetic basis helps initiate possible treatment, delineate prognosis, and identify risks for future pregnancies. [ncbi.nlm.nih.gov]
Diagnosis and Prognosis: This condition requires ophthalmologic, pediatric, and orthopedic collaboration for diagnosis. Orthopedic repair is indicated for fractures and scoliosis. [disorders.eyes.arizona.edu]

PROGNOSIS: Long term follow-up is lacking in this rare disorder. However, repeated fractures can lead to deformity disabilities. [wohproject.org]
Etiology
While several genes have been identified so far related to microphthalmia, the genetic etiology of the disease has not been fully understood because of genetic heterogeneity observed in this disease. [ncbi.nlm.nih.gov]

Bisphosphonates allows fracture prevention, the catch-up of bone mineral density and improvement in mobility in children with OPPG. New drugs favoring osteoblast function and osteoclast inhibition are potential candidates in the treatment of OPPG. [tandfonline.com]
