Vici syndrome is a rare relentlessly progressive congenital multisystem disorder characterised by five principal features of callosal agenesis, cataracts, cardiomyopathy, combined immunodeficiency, and oculocutaneous hypopigmentation. Profound developmental delay, progressive failure to thrive, and acquired microcephaly are almost universal, suggesting an evolving (neuro) degenerative component. In most patients there is additional variable multisystem involvement that may affect virtually any organ system, including lungs, thyroid, liver, and kidneys. A skeletal myopathy is consistently associated. Recent studies identified mutations in the gene EPG5 as the cause of Vici syndrome. EPG5 is involved in autophagy, an evolutionarily conserved lysosomal degradation process that is essential for cell homeostasis.

Recessive mutations in EPG5 cause Vici syndrome, a multisystem disorder with defective autophagy.
