Abstract

D-bifunctional protein (DBP) deficiency is an autosomal recessive inborn error of peroxisomal fatty acid oxidation. The clinical presentation of DBP deficiency is usually very severe, but a few patients with a relatively mild presentation have been identified. In this article, we report the mutational spectrum of DBP deficiency on the basis of molecular analysis in 110 patients. We identified 61 different mutations by DBP cDNA analysis, 48 of which have not been reported previously. The predicted effects of the different disease-causing amino acid changes on protein structure were determined using the crystal structures of the (3R)-hydroxyacyl-coenzyme A (CoA) dehydrogenase unit of rat DBP and the 2-enoyl-CoA hydratase 2 unit and liganded sterol carrier protein 2-like unit of human DBP. The effects ranged from the replacement of catalytic amino acid residues or residues in direct contact with the substrate or cofactor to disturbances of protein folding or dimerization of the subunits. To study whether there is a genotype-phenotype correlation for DBP deficiency, these structure-based analyses were combined with extensive biochemical analyses of patient material (cultured skin fibroblasts and plasma) and available clinical information on the patients. We found that the effect of the mutations identified in patients with a relatively mild clinical and biochemical presentation was less detrimental to the protein structure than the effect of mutations identified in those with a very severe presentation. These results suggest that the amount of residual DBP activity correlates with the severity of the phenotype. From our data, we conclude that, on the basis of the predicted effect of the mutations on protein structure, a genotype-phenotype correlation exists for DBP deficiency.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
