The legend of Fig. 4 contains two incorrect lane references in the second sentence. A corrected legend follows.

Fig. 4 Western-blot analysis of liver homogenate. We separated an equivalent of 2 mU citrate synthase from affected individual 21 of family 1-F (lane 2) and three normal control individuals (lanes 1, 3 and 4) using SDS–PAGE, electroblotted the synthase and incubated it with anti-dGK antibodies. Molecular weight markers were run in the flanking slots. The DGK band is near the MW 29,000 band. The presence of a number of bands weakly cross-reactive with the DGK polyclonal antiserum shows that the proteins in the affected individual's sample were not affected.
