Genes affected

COG4 (HGNC:18620): (component of oligomeric golgi complex 4) The protein encoded by this gene is a component of an oligomeric protein complex involved in the structure and function of the Golgi apparatus. Defects in this gene may be a cause of congenital disorder of glycosylation type IIj. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Aug 2010]

The c.2308C>T (p.R770C) alteration is located in exon 19 (coding exon 19) of the COG4 gene. This alteration results from a C to T substitution at nucleotide position 2308, causing the arginine (R) at amino acid position 770 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
