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]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 16-23388624-C-CT is Benign according to our data. Variant chr16-23388624-C-CT is described in ClinVar as [Likely_benign]. Clinvar id is 1203781.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0195 (2387/122436) while in subpopulation EAS AF= 0.0432 (181/4186). AF 95% confidence interval is 0.0381. There are 44 homozygotes in gnomad4. There are 1146 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 44 AR gene
