Genes affected
COG1 (HGNC:6545): (component of oligomeric golgi complex 1) The protein encoded by this gene is one of eight proteins (Cog1-8) which form a Golgi-localized complex (COG) required for normal Golgi morphology and function. It is thought that this protein is required for steps in the normal medial and trans Golgi-associated processing of glycoconjugates and plays a role in the organization of the Golgi-localized complex.

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.2864G>A (p.R955K) alteration is located in exon 14 (coding exon 14) of the COG1 gene. This alteration results from a G to A substitution at nucleotide position 2864, causing the arginine (R) at amino acid position 955 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
