Perthes-Like Disorder in a Child with Atypical Bohring-Opitz Syndrome

Abstract

Case: Bohring-Opitz syndrome is characterized by facial dysmorphism, intellectual disability, specific upper-limb posturing, and developmental delay. We report a case of 14-year-old girl with bilateral hip pain and loss of mobility. Clinical exome sequencing showed a proband with a heterozygous pathogenic nonsense variant in ASXL1 gene.

Conclusion: The Perthes-like clinical and radiological features in the hip and the absence of classical upper-limb features are a new phenotype and hence presented here.
