dbSNP rs764545607: COG7:p.Asp364Tyr (chr16-23418747-C-A) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_153603.4(COG7):c.1090G>T(p.Asp364Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,542 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D364N) has been classified as Uncertain significance.

Genes affected

COG7 (HGNC:18622): (component of oligomeric golgi complex 7) The protein encoded by this gene resides in the golgi, and constitutes one of the 8 subunits of the conserved oligomeric Golgi (COG) complex, which is required for normal golgi morphology and localization. Mutations in this gene are associated with the congenital disorder of glycosylation type IIe.[provided by RefSeq, May 2010]
