We compared C26:0-LPC levels in our Pex7 deficient mice to a previously reported mouse model of the peroxisome biogenesis disorder Zellweger Spectrum disorder (Pex5 KO) and the peroxisomal enzyme/transporter deficiency X-linked adrenoleukodystrophy (Abcd1 KO). Here, PEX7 is linked to peroxisome biogenesis disorder.
