Abstract:
:Complementation studies, using fused cell lines from patients with peroxisomal disorders, have shown correction of defective plasmalogen synthesis and phytanic acid oxidation as well as an increase in the number of peroxisomes. At least six complementation groups have been reported. We demonstrate here that complementing cell lines also acquire the ability to oxidize very long chain fatty acids (VLCFA), and that complementation groups defined with this technique are identical to those reported previously when plasmalogen synthesis was used as the criterion for complementation. This VLCFA complementation technique is of particular value in the study of patients in whom defective VLCFA is the only or major enzymatic defect, and we show complementation between cell lines from two patients each with an isolated defect in one of the peroxisomal fatty acid beta-oxidation enzymes.
