COG7

Chr 16AR

component of oligomeric golgi complex 7

The COG7 protein is a subunit of the conserved oligomeric Golgi (COG) complex that is required for normal Golgi morphology and function. Mutations cause congenital disorder of glycosylation type IIe, an autosomal recessive condition affecting protein glycosylation. This gene shows moderate constraint against loss-of-function variants (LOEUF 0.661) and has detailed clinical information available in GeneReviews.
