COG6

Chr 13AR

component of oligomeric golgi complex 6

Also known as: CDG2L, COD2, SHNS

This gene encodes a subunit of the conserved oligomeric Golgi complex that maintains normal Golgi apparatus structure and function, specifically as part of the lobe B sub-complex with COG components 5, 7, and 8. Mutations cause congenital disorder of glycosylation type IIl and Shaheen syndrome, both inherited in an autosomal recessive pattern. The gene shows no significant constraint against loss-of-function variants (pLI near zero, LOEUF ~1), which is consistent with the recessive inheritance pattern where heterozygous carriers are typically unaffected.
