Osteoporosis Pseudoglioma Syndrome

Osteoporosis pseudoglioma syndrome is characterized by intellectual disability, osteoporosis of bones and eye abnormalities. We report, a 14-year-old female child presented with walking difficulty with frequent falls followed by deformity of left leg. On examination, bilateral micropthalmia, microcornea, corneal clouding, vitreo-retinal detachment, and atrophic irises. She had deformity of left lower limb, anterior bowing of both tibia, lax skin, hyperextensible joints. Skeletal survey showed severe osteoporosis with fracture of left femur and fish mouth vertebra. She had normal serum calcium, phosphorus, and alkaline phosphatase levels. Targeted next generation testing revealed homozygous pathogenic variant in exon 6 at c.1096G>A/p.V366 M and confirmed by Sanger sequencing. Early diagnosis and treatment are helpful in preventing further fractures and osteoporosis.
