D-bifunctional protein (DBP) deficiency, a fatal peroxisomal enzyme disorder, typically manifests with life-threatening symptoms in the first two years of childhood. We present the case of an infant with elevated lysophosphatidylcholine C26:0 (C26:0-LPC) levels identified during X-linked adrenoleukodystrophy (ALD) screening, leading to a diagnosis of DBP deficiency due to a homozygous HSD17B4 c.1041T>A, p.(Tyr347Ter) variant. Starting at two months of age, the infant experienced seizures, hypotonia, and developmental delays, prompting the initiation of experimental treatment with the readthrough agent PTC124 (ataluren) at six months. The treatment led to a decrease in C26:0-LPC levels from 0.65 μM to 0.53 μM; concomitant fish oil supplementation transiently increased C26:0-LPC to 0.74 μM before returning to 0.53 μM after cessation of supplementation. The patient demonstrated improved swallowing and progressive motor and speech development during a two-year treatment period, with no further seizures. This case report highlights the potential of nonsense readthrough therapy for peroxisomal disorders, a group of metabolic diseases that currently lack targeted treatments. |
