Insights
Congenital horizontal gaze paralysis, a rare disorder, is often linked to early-onset severe scoliosis. Early evaluation for scoliosis in affected children is crucial for diagnosis and genetic counseling.
Area of Science:
- Ophthalmology
- Genetics
- Orthopedics
Background:
- Congenital horizontal gaze paralysis (CHGP) is a rare neurological disorder affecting eye movement.
- CHGP can be associated with significant early-onset scoliosis, impacting spinal health.
Observation:
- This report details two sisters diagnosed with CHGP and severe scoliosis.
- A pericentric inversion of chromosome 12 was noted but deemed incidental to the syndrome.
Findings:
- The clinical presentation suggests a potential syndrome linking CHGP and early-onset scoliosis.
- The inheritance pattern appears to be autosomal recessive, based on the affected siblings.
Implications:
- Children diagnosed with CHGP require thorough orthopedic evaluation for scoliosis.
- Early diagnosis enables timely intervention, management, and genetic counseling for families.
- This highlights the importance of a multidisciplinary approach in managing rare genetic disorders.
Abstract:
Congenital horizontal gaze paralysis is a rare disorder which may be associated with severe scoliosis of early onset. We present the clinical findings of two sisters with this syndrome. The additional finding of a unique pericentric inversion of chromosome 12 is considered to be incidental. Every child with congenital horizontal gaze paralysis should be evaluated for a possibly associated scoliosis. If present, a diagnosis of this presumably autosomal recessive syndrome can be made with appropriate treatment and genetic counseling.
