Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 2P and 3B. PM2 BP4_Moderate BP7

The NM_016128.4(COPG1):​c.366C>A​(p.Gly122Gly) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. G122G) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: COPG1 NM_016128.4 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.0530

Genes affected

COPG1 (HGNC:2236): (COPI coat complex subunit gamma 1) Predicted to enable structural molecule activity. Predicted to be involved in several processes, including Golgi vesicle transport; establishment of Golgi localization; and organelle transport along microtubule. Located in Golgi apparatus.
