Abstract

Mutations in the . TARDBP gene are described as a cause of autosomal dominant amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration (FTLD) with or without motor neuron involvement, and, recently, Parkinson's disease (PD). We hereby describe a family presenting the A382T mutation; two subjects were in the homozygous state, and two were in the heterozygous state. The index case, carrying the A382T mutation in the homozygous state, had an 8-year history of sporadic PD and 6 years later developed ALS and FTLD; his brother, carrying the same mutation in the homozygous state, and the other two family member carriers of the same mutation in the heterozygous state were without neurological signs and symptoms. This family confirms that mutation in transactive response (TAR)-DNA-binding protein 43 (TDP43), both the homozygous and the heterozygous state, may be found in subjects with different clinical conditions ranging from neurological disease to non-neurological disease. In addition, the aforementioned findings add to the debate for the ethical and psychological dilemmas about genetic counseling.
