The chart on page 675 of the Perspective "Molecular genetics of neurological diseases" by Joseph B. Martin (29 Oct., p. 674) should have stated that the chromosome locus for spinobulbar muscular atrophy is Xq12 (not Xq21.3) and that the length of the CAG repeat in the androgen receptor gene in patient samples is 40-62 (not 30-62). In the discussion on page 676 of Alzheimer's disease among families of Volga-German descent, the exclusion chromosome numbers should have been 14, 19, and 21 (not 20).
