The numbering of the SOX3 nucleotide variants should read 1050 C/T and 1173 A/C (nucleotide numbering according to GenBank accession number X71135). We stress that the codon numbering is correct and that the nucleotide variants are silent changes in the third base position of tyrosine (codon 203) and alanine (codon 244) respectively. The results and conclusions of the study are unaffected. We regret any inconvenience this error may have caused.
