Gaze palsy, familial horizontal, with progressive scoliosis(HGPPS1)

Intellectual Product
Sources: HPO, OMIM, Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).

HGPPS is an autosomal recessive neurologic disorder characterized by eye movement abnormalities apparent from birth and childhood-onset progressive scoliosis. These features are associated with a developmental malformation of the brainstem including hypoplasia of the pons and cerebellar peduncles and defective decussation of certain neuronal systems. Cognitive function is normal (summary by Bosley et al., 2005). Genetic Heterogeneity of Familial Horizontal Gaze Palsy With Progressive Scoliosis See also HGPPS2 (617542), caused by mutation in the DCC gene (120470) on chromosome 18q21. [from OMIM]

Additional description

From GHR
Horizontal gaze palsy with progressive scoliosis (HGPPS) is a disorder that affects vision and also causes an abnormal curvature of the spine (scoliosis). People with this condition are unable to move their eyes side-to-side (horizontally). As a result, affected individuals must turn their head instead of moving their eyes to track moving objects. Up-and-down (vertical) eye movements are typically normal.In people with HGPPS, an abnormal side-to-side curvature of the spine develops in infancy or childhood. It tends to be moderate to severe and worsens over time. Because the abnormal spine position can be painful and interfere with movement, it is often treated with surgery early in life.

Horizontal supranuclear gaze palsy
MedGen UID:
Concept ID:
Disease or Syndrome
A supranuclear gaze palsy is an inability to look in a horizontal direction as a result of cerebral impairment. There is a loss of the voluntary aspect of eye movements, but, as the brainstem is still intact, all the reflex conjugate eye movements are normal.
