In the first sentence of the final paragraph, the locus 16q23.4 is incorrect. The corrected sentence is “Our results suggest that CAG/CTG repeat expansions of about 40 or more triplets at the HDL2 locus on 16q24.3 cause HDL2.”

In Fig. 2e, the cDNA that is labeled '(CTG)n=polyalanine' should be labeled: '(CTG)n=polyleucine'. The second to last sentence of the legend to Fig. 2 is missing a comma; the sentence should be: “Depending on the splice acceptor site, the repeat is in a 3′ untranslated region, in the frame to encode polyalanine, or in the frame to encode polyleucine.”
