Duane retraction syndrome 2

Preferred Label : Duane retraction syndrome 2;

Symbol : DURS2;

CISMeF acronym : DURS2;

Type : Phenotype, molecular basis known;

Description : Duane retraction syndrome (DURS) is a congenital disorder characterized by restricted horizontal eye movement with globe retraction and palpebral fissure narrowing on attempted adduction. DURS is observed in approximately 0.1% of the general population, accounts for 1 to 5% of all strabismus, and if untreated in childhood can result in loss of binocular vision and amblyopia. Postmortem examinations of individuals with sporadic DURS have shown absence of the abducens motor neurons and abducens cranial nerve on the affected side(s), and aberrant innervation of the lateral rectus by axons of the oculomotor nerve that normally innervate the medial rectus muscle. Most patients are affected unilaterally and have no family history of the disorder (summary by Miyake et al., 2010). For a discussion of genetic heterogeneity of Duane retraction syndrome, see DURS1 (126800).;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in chimerin 1 gene (CHN1, 118423.0001);

Prefixed ID : #604356;
