Our study further widens the geographic range for the origin of disease‐causing heterozygous missense mutations of the SETX gene, which have already been implicated in ALS in patients from different countries (Avemaria et al., 2011; Hirano et al., 2011; Kenna et al., 2013; Saracchi et al., 2014). The gene discussed is SETX; the disease is amyotrophic lateral sclerosis.
