Genes affected
COG3 (HGNC:18619): (component of oligomeric golgi complex 3) This gene encodes a component of the conserved oligomeric Golgi (COG) complex which is composed of eight different subunits and is required for normal Golgi morphology and localization. Defects in the COG complex result in multiple deficiencies in protein glycosylation. The protein encoded by this gene is involved in ER-Golgi transport.[provided by RefSeq, Jun 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.79C>T (p.R27W) alteration is located in exon 1 (coding exon 1) of the COG3 gene. This alteration results from a C to T substitution at nucleotide position 79, causing the arginine (R) at amino acid position 27 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
