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.

VCF1 (HGNC:25918): (VCP nuclear cofactor family member 1)

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 04, 2024The c.2816C>T (p.P939L) alteration is located in exon 14 (coding exon 14) of the COG1 gene. This alteration results from a C to T substitution at nucleotide position 2816, causing the proline (P) at amino acid position 939 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
