A Lawrence, F Hol, A Aggarwal, et al. Hyperimmunoglobulinaemia D syndrome in India: report of two siblings with a novel mutation. Ann Rheum Dis 2006;65:1674–6. In figure 1(B) the component labelled ‘Intron 2′ should actually be labelled ‘Intron 3.’ In addition, figure 1(B) legend should read: (B) Shows the electrospherogram with sequence identification of the deletion of a T nucleotide in intron 3. This mutation, IVS3+2 delT, is predicted to affect correct splicing of the exon, resulting in a shift of the reading frame.
