While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 210 amino acid(s) of the CLDN14 protein. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with CLDN14-related conditions. ClinVar contains an entry for this variant (Variation ID: 1064997). This variant disrupts a region of the CLDN14 protein in which other variant(s) (p.Arg81His) have been determined to be pathogenic (PMID: 22246673, 23235333). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
