GeneDx RCV000187129 SCV000240705 uncertain significance not provided 2018-09-14 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the CLN8 gene. The P260L variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The P260L variant is observed in 64/24030 (0.3%) alleles from individuals of African background in large population cohorts (Lek et al., 2016). The P260L variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. In-silico analyses, including protein predictors and evolutionary conservation, support a deleterious effect. Missense variants in nearby residues have been reported in the Human Gene Mutation Database in individuals with neuronal ceroid lipofuscinosis (Stenson et al., 2014). Based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.

This variant is present in ClinVar (Variation ID:205196). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain.
