Summaries for X-Linked Infantile Nystagmus

KEGG : 36 Nystagmus is an eye movement disorder in which one or both eyes are in constant movement. Nystagmus that occur independent of these known ocular or systemic diseases is referred to as congenital motor nystagmus (CMN) or idiopathic congenital nystagmus (ICN). It can be inherited as an autosomal dominant, an autosomal recessive, or an X-linked trait. At least six genetic loci for CMN have been suggested, including three loci for autosomal dominant CMN, and three loci for X-linked CMN. A variety of mutations in the FRMD7 gene have been identified in many families with an X-linked recessive pattern. Another mutation associated with X-linked CMN is GPR143.

MalaCards based summary : X-Linked Infantile Nystagmus, also known as idiopathic infantile nystagmus, is related to congenital nystagmus 1 and nystagmus 3, congenital, autosomal dominant. An important gene associated with X-Linked Infantile Nystagmus is FRMD7 (FERM Domain Containing 7). Affiliated tissues include eye.

MedlinePlus Genetics : 43 X-linked infantile nystagmus is a condition characterized by abnormal eye movements. Nystagmus is a term that refers to involuntary side-to-side movements of the eyes. In people with this condition, nystagmus is present at birth or develops within the first six months of life. The abnormal eye movements may worsen when an affected person is feeling anxious or tries to stare directly at an object. The severity of nystagmus varies, even among affected individuals within the same family. Sometimes, affected individuals will turn or tilt their head to compensate for the irregular eye movements.
