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]

Uncertain significance, criteria provided, single submitter	clinical testing	Athena Diagnostics	Feb 09, 2023	Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is uninformative in assessment of its pathogenicity (http://gnomad.broadinstitute.org). This variant has been identified in at least one individual with amyotrophic lateral sclerosis. Computational tools predict that this variant is damaging. -

The p.Q314L variant (also known as c.941A>T), located in coding exon 7 of the OPTN gene, results from an A to T substitution at nucleotide position 941. The glutamine at codon 314 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the supporting evidence, this variant is unlikely to be causative of autosomal dominant amyotrophic lateral sclerosis; however, its contribution to the development of autosomal recessive amyotrophic lateral sclerosis is uncertain. -

This sequence change replaces glutamine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 314 of the OPTN protein (p.Gln314Leu). This variant is present in population databases (rs142812715, gnomAD 0.03%). This missense change has been observed in individual(s) with clinical features of OPTN-related conditions (PMID: 21613650, 28089114, 31000212, 32028661, 36133075). ClinVar contains an entry for this variant (Variation ID: 266060). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on OPTN protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
