Horizontal gaze palsy with progressive scoliosis (HGPPS): expanding ROBO3 molecular spectrum and refining clinical-neuroimaging phenotypes
{{output}}
Horizontal gaze palsy with progressive scoliosis (HGPPS) is a rare autosomal recessive disorder caused by biallelic ROBO3 variants, characterized by congenital horizontal gaze restriction, early-onset scoliosis, and distinctive hindbrain malformations. We repo... ...
