Genes affected

COG8 (HGNC:18623): (component of oligomeric golgi complex 8) This gene encodes a protein that is a component of the conserved oligomeric Golgi (COG) complex, a multiprotein complex that plays a structural role in the Golgi apparatus, and is involved in intracellular membrane trafficking and glycoprotein modification. Mutations in this gene cause congenital disorder of glycosylation, type IIh, a disease that is characterized by under-glycosylated serum proteins, and whose symptoms include severe psychomotor retardation, failure to thrive, seizures, and dairy and wheat product intolerance.

ENSG00000260371 (HGNC:):

NIP7 (HGNC:24328): (nucleolar pre-rRNA processing protein NIP7) Enables RNA binding activity. Predicted to be involved in ribosomal large subunit biogenesis. Located in cytosol; nucleolus; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -7 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.54).
• BP6: Variant 16-69339196-G-C is Benign according to our data. Variant chr16-69339196-G-C is described in ClinVar as Likely_benign. ClinVar VariationId is 2082443.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=2.05 with no splicing effect.
