HTT full‐penetrance pathogenic repeat expansions, the genetic cause of Huntington's disease (HD), have been recently reported in a minority of frontotemporal dementia/amyotrophic lateral sclerosis (ALS) patients (0.13%). We analyzed HTT CAG repeats in an Italian cohort of ALS patients (n = 467) by repeat‐primed polymerase chain reaction. One patient harbored two expanded alleles in the HTT gene (42 and 37 CAG repeats). The absence of HD typical symptoms and the clinical picture consistent with ALS, corroborated by the diagnostic assessment, apparently excluded a misdiagnosis of HD.
