Genes affected

COG6 (HGNC:18621): (component of oligomeric golgi complex 6) This gene encodes a subunit of the conserved oligomeric Golgi complex that is required for maintaining normal structure and activity of the Golgi apparatus. The encoded protein is organized with conserved oligomeric Golgi complex components 5, 7 and 8 into a sub-complex referred to as lobe B. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Feb 2009]

Ambry Genetics

Mar 04, 2024

The c.7G>C (p.E3Q) alteration is located in exon 1 (coding exon 1) of the COG6 gene. This alteration results from a G to C substitution at nucleotide position 7, causing the glutamic acid (E) at amino acid position 3 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
