Genes affected

OPTN (HGNC:17142): (optineurin) This gene encodes the coiled-coil containing protein optineurin. Optineurin may play a role in normal-tension glaucoma and adult-onset primary open angle glaucoma. Optineurin interacts with adenovirus E3-14.7K protein and may utilize tumor necrosis factor-alpha or Fas-ligand pathways to mediate apoptosis, inflammation or vasoconstriction. Optineurin may also function in cellular morphogenesis and membrane trafficking, vesicle trafficking, and transcription activation through its interactions with the RAB8, huntingtin, and transcription factor IIIA proteins. Alternative splicing results in multiple transcript variants encoding the same protein. [provided by RefSeq, Jul 2008]

CCDC3 (HGNC:23813): (coiled-coil domain containing 3) Involved in negative regulation of gene expression; negative regulation of lipid metabolic process; and negative regulation of tumor necrosis factor-mediated signaling pathway. Located in endoplasmic reticulum and extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000289266 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BP6: Variant 10-13100192-C-A is Benign according to our data. Variant chr10-13100192-C-A is described in ClinVar as Benign. ClinVar VariationId is 299203.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000486 (74/152322) while in subpopulation SAS AF = 0.0151 (73/4834). AF 95% confidence interval is 0.0123. There are 1 homozygotes in GnomAd4. There are 64 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
