Abstract:
A hexanucleotide repeat expansions in the first intron of C9ORF72 has been shown to be responsible for a high number of familial cases of amyotrophic lateral sclerosis and/or frontotemporal lobar degeneration. The same mutation has been described in a patient with bipolar disorder, but up to now, not in patients suffering from schizophrenia. We determined the frequency of the C9ORF72 hexanucleotide repeat expansions in a population of 298 patients with schizophrenia or schizoaffective disorder. The pathogenic repeat expansion was detected in 2 patients (0.67%). Both of them presented with auditory hallucinations and had comorbid alcohol abuse. In addition, a positive family history for psychiatric and/or neurodegenerative diseases was present. The repeat expansion in the C9ORF72 gene is a rare, but possible, cause of schizophrenic spectrum disorders. We cannot rule out however whether the number of repeats influence the phenotype.
