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 was made for transcript

Our verdict: Benign. The variant received -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 VariationId is 194974.
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 the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 15 AR,AD gene
