A recent study suggested an association between rare, non-synonymous variants in the gene encoding tumor protein p73 (TP73) and amyotrophic lateral sclerosis (ALS) — a progressive, fatal neurodegenerative disease. The original association was based on a case-control analysis with relatively small sample size. While functional data were presented to substantiate these claims, it remains unclear whether the results demonstrate clinical significance; additionally, the modelled null alleles had been recently reported to cause a severe pediatric disorder characterized by impaired mucociliary clearance and lissencephaly. Here, we aimed to replicate the proposed genetic association between TP73 and ALS using the two largest publicly available ALS sequencing datasets as hosted by the ALS Knowledge Portal (n = 3864 cases and n = 7839 controls) and the Project MinE ALS browser (n = 4366 cases and n = 1832 controls) for a total of 8230 ALS cases and 9671 controls. We did not observe an enrichment of rare, protein-coding variants in the ALS cases and surprisingly identified a relatively large number of controls carrying rare, non-synonymous variants in TP73 (n = 65). Based on these results we conclude that TP73 most likely does not predispose to ALS.
