The role of the microtubule cytoskeleton in neurodevelopmental disorders. Although the term "congenital nystagmus" is often used synonymously, nystagmus is seldom diagnosed at birth. Other causes of nystagmus in infants are coloboma and achromatopsia. National Library of Medicine cause a jerk nystagmus with linear or constant velocity slow phase drifts (Figure 2b). Because we could not obtain optical coherence tomography, it is possible that a mild degree of foveal hypoplasia or retinal dystrophy co-exists. Results: FOIA Optic nerve hypoplasia has been reported with TUBA1A, TUBB2B, and TUBA8 mutations, suggesting that tubulin gene mutations, in general, can cause optic nerve hypoplasia [28,29,30]. 1.

Therefore, pediatric ophthalmologists should keep in mind that the clinical features of the TUBB3 syndrome are so diverse that only nystagmus could appear as the main presenting sign. Congenital nystagmus, or infantile nystagmus syndrome, typically appears in the first few months of life as conjugate horizontal nystagmus that remains horizontal even in vertical gaze. Infantile nystagmus (IN), previously known as congenital nystagmus, is an involuntary to-and-fro movement of the eyes that persists throughout life.

Other forms of acquired nystagmus are due to brainstem, cerebellar or metabolic diseases. The diagnosis of FRMD7-related infantile nystagmus (FIN) can be challenging as numerous causes of infantile nystagmus can present with conjugate horizontal oscillations of the eyes and reduced visual acuity. Infantile nystagmus syndrome is a genetically heterogeneous disorder in which an involuntary oscillation of the eyes begins within the first 6 months of life [].The oscillations usually start at 2 to 3 months of age when motor and visual functions develop and persist throughout life [].The prevalence of infantile nystagmus syndrome was estimated from 1 in 3000 to 1 in 1000 [3,4].
