Description : Congenital fibrosis of the extraocular muscles (CFEOM) encompasses several different
inherited strabismus syndromes characterized by congenital restrictive ophthalmoplegia
affecting extraocular muscles innervated by the oculomotor and/or trochlear nerves.
If all affected members of a family have classic CFEOM with bilateral involvement
and inability to raise the eyes above midline, the phenotype is classified as CFEOM1
(135700). CFEOM2 (602078) shows autosomal recessive inheritance. CFEOM3 is characterized
by autosomal dominant inheritance of a more variable phenotype than classic CFEOM1.
Individuals with;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the tubulin beta-3 gene (TUBB3, 602661.0001);
