Errors in Table. In the Original Contribution by Régal et al titled “The G93C Mutation in Superoxide Dismutase 1: Clinicopathologic Phenotype and Prognosis,” published in the February issue of the ARCHIVES (2006;63:262-267), several errors occurred on page 265 in Table 2. In that table, the asterisk next to the column heading “D101N” should have been a dagger to refer to “Reduced penetrance and apparently sporadic cases.” In addition, the sideheadings “Other neurodegeneration” and “LBHI” should have been indented to indicate that these are also pathologic findings, and the following definitions should have appeared at the end of the Abbreviations footnote: “(for UMN signs: −, absent; +, hyperreflexia; ++, Babinski sign or spasticity).” The corrected table is reprinted here with its footnotes.
