Abstract


Background: Opsismodysplasia (OPSMD) is an extremely rare and severe autosomal recessive skeletal dysplasia that is under the category of severe spondylodysplastic dysplasia. It is characterized by delayed bone maturation, and affected patients are identified by a peculiar craniofacioskeletal dysmorphism in the form of wide anterior fontanelle, depressed nasal bridge, anteverted nares, and short limbs and feet. Radiologically, they are characterized by severe platyspondyly, squared metacarpals, delayed skeletal ossification, and metaphyseal cupping. Case Presentation: We present the clinical and radiological features of a 14-month-old boy with a homozygous, likely pathogenic variant in INPPL1 gene c.2627dup (p.Pro977Thrfs*7) consistent with the diagnosis of OPSMD. He also has dilated cardiomyopathy. Conclusion: OPSMD is an uncommon form of skeletal dysplasia that should be suspected in the context of short stature with characteristic radiological features. Up to now, no definitive therapeutic measures are available, and hence preventive measures are essential in the management of families with affected members.
