A couple of disease-associated minisatellites have been identified recently; for example, 100–3000 30-mer copies were found to be associated with schizophrenia and bipolar disorder20, over 200 25-mer copies in ABCA7 were found to be specific to Alzheimer’s disease with an odds ratio of 4.521, and 69-mer repeats in WDR7 were identified in amyotrophic lateral sclerosis (ALS)22. Here, ABCA7 is linked to amyotrophic lateral sclerosis.
