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]

The c.782A>G (p.H261R) alteration is located in exon 7 (coding exon 7) of the COG3 gene. This alteration results from a A to G substitution at nucleotide position 782, causing the histidine (H) at amino acid position 261 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
