Genes affected
COG4 (HGNC:18620): (component of oligomeric golgi complex 4) The protein encoded by this gene is a component of an oligomeric protein complex involved in the structure and function of the Golgi apparatus. Defects in this gene may be a cause of congenital disorder of glycosylation type IIj. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Aug 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.53).
BP6
Variant 16-70481070-G-C is Benign according to our data. Variant chr16-70481070-G-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 194974.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=1}.
BP7
Synonymous conserved (PhyloP=0.382 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000269 (41/152356) while in subpopulation SAS AF= 0.00828 (40/4830). AF 95% confidence interval is 0.00625. There are 1 homozygotes in gnomad4. There are 34 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 15 AR gene
