Description

Variant summary: CLN3 c.206C>T (p.Ser69Leu) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 5.6e-05 in 249602 control chromosomes (gnomAD). This frequency is not higher than expected for a pathogenic variant in CLN3 causing Neuronal Ceroid-Lipofuscinosis (Batten Disease) (5.6e-05 vs 0.0016), allowing no conclusion about variant significance. c.206C>T has been reported in the literature in at-least one individual affected with inherited retinal degenration without evidence for causality (Zampaglione_2020). This report does not provide unequivocal conclusions about association of the variant with Neuronal Ceroid-Lipofuscinosis (Batten Disease). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 32037395). ClinVar contains an entry for this variant (Variation ID: 205104, all VUS). Based on the evidence outlined above, the variant was classified as uncertain significance.
