This rare and multisystem autosomal recessive disorder is linked to a variable phenotype of global developmental delay, neuromuscular abnormalities, and alacrima, and it lacks effective treatment.

Furthermore, fish brain molecular and biochemical characterization was performed by gene expression analysis and immunoblotting techniques. Impaired proteostasis was evident in the brain of the mutant zebrafish, including accumulation of poly\u2010ubiquitinated proteins and amyloid fibril aggregation. The mutant fish featured neuromuscular abnormalities and significant aquaporin1\u2010protein reduction in the eyes and brain. The zebrafish model of NGLY1 deficiency provides an ideal platform for studying the molecular and biochemical mechanisms underlying NGLY1\u2010CDDG in humans. Our novel findings of impaired protein homeostasis encompassing amyloid fibril aggregation (folding) and poly\u2010ubiquitinated protein accumulation (degradation) in the brains of mutant zebrafish offer new insights into the brain pathology associated with NGLY1 deficiency. These discoveries may also advance our understanding of other neurodegenerative disorders and facilitate the identification of potential therapeutic targets.\n                    <\/jats:p>\n
