Ophthalmoplegia, familial static

MedGen UID:
371666
Concept ID:
C1833839
Disease or Syndrome
Synonyms: EXTERNAL OPHTHALMOPLEGIA, NONPROGRESSIVE, CONGENITAL HEREDITARY
Modes of inheritance:
Autosomal dominant inheritance
MedGen UID:
141047
Concept ID:
C0443147
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 heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Clinical features

Anisocoria
MedGen UID:
1944
Concept ID:
C0003079
Finding
Anisocoria, or unequal pupil size, may represent a benign physiologic variant or a manifestation of disease.
Ptosis
MedGen UID:
2287
Concept ID:
C0005745
Disease or Syndrome
Drooping of the upper lid due to deficient development or paralysis of the levator palpebrae muscle.
Nystagmus
MedGen UID:
45166
Concept ID:
C0028738
Disease or Syndrome
Involuntary movements of the eye that are divided into two types, jerk and pendular. Jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction, and is usually caused by central or peripheral vestibular dysfunction. Pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life. (Adams et al., Principles of Neurology, 6th ed, p272)
Ophthalmoplegia
MedGen UID:
45205
Concept ID:
C0029089
Sign or Symptom
Paralysis of one or more extraocular muscles that are responsible for eye movements.
