Genes affected

COG1 (HGNC:6545): (component of oligomeric golgi complex 1) The protein encoded by this gene is one of eight proteins (Cog1-8) which form a Golgi-localized complex (COG) required for normal Golgi morphology and function. It is thought that this protein is required for steps in the normal medial and trans Golgi-associated processing of glycoconjugates and plays a role in the organization of the Golgi-localized complex.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0965479).

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000397 (58/1461868) while in subpopulation SAS AF = 0.000441 (38/86258). AF 95% confidence interval is 0.00033. There are 0 homozygotes in GnomAdExome4. There are 33 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
