34 Possible Causes for Genetic Anticipation Has Been Observed, Interictal Downbeat Nystagmus

  • Spinocerebellar Ataxia Type 4

    Initial examination disclosed a central type of positional nystagmus (conjugate downbeat nystagmus that did not fatigue with repeated positioning).[jnnp.bmj.com] About a year later, she noticed mild interictal imbalance.[jnnp.bmj.com]

  • Spinocerebellar Ataxia Type 5

    In 1994, Ranum and colleagues identified a ten-generation American kindred with a relatively mild autosomal dominant form of spinocerebellar ataxia (Ranum et al., 1994). The mutation was mapped to the centromeric region of chromosome 11, and the disorder designated SCA5 (Ranum et al., 1994). Using a multifaceted[…][ncbi.nlm.nih.gov]

  • Eating Disorder

    Similarly to what has been observed in schizophrenia, 8, 24, 25 the presence of a greater number of obstetric complications seems to anticipate the onset of the illness.[doi.org] Candidate factors could be sex, genetic liability, and other environmental risk factors.[doi.org]

    According to Baloh and others (1997), EA2 is characterized by a progressive ataxia with interictal rebound nystagmus evoked by gaze, as well as downbeating nystagmus.[dizziness-and-balance.com] Initial examination disclosed a central type of positional nystagmus (conjugate downbeat nystagmus that did not fatigue with repeated positioning).[jnnp.bmj.com] About a year later, she noticed mild interictal imbalance.[jnnp.bmj.com]
