In memory of Millie who had Zellweger Spectrum Disorder, otherwise known as GPD (Generalised Peroxisomal Disorder), is a very rare genetic condition belonging to a group of diseases called Peroxisomal Biogensis Disorder (PBD). Most children don’t live into adulthood and deal with global developmental delays, deaf-blindness/multi-sensory loss and a plethora of other health issues. Life with Zellweger Spectrum Disorder can feel incredibly lonely.
