Genes affected
CLN3 (HGNC:2074): (CLN3 lysosomal/endosomal transmembrane protein, battenin) This gene encodes a protein that is involved in lysosomal function. Mutations in this, as well as other neuronal ceroid-lipofuscinosis (CLN) genes, cause neurodegenerative diseases commonly known as Batten disease or collectively known as neuronal ceroid lipofuscinoses (NCLs). Many alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2008]

ame nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000418137, PMID:24154662, PS1_S). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 24154662, 29049447, PM3_M). Itwas co-segregated with Ceroid lipofuscinosis, neuronal, 3 in multiple affected family members with additional meioses (PMID: 24154662, PP1_M). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.873, 3CNET: 0.99, PP3_P). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000067, PM2_M). STherefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -

The p.Arg405Trp variant in CLN3 was identified in an individual with Retinitis pigmentosa, via a collaborative study between the Broad Institute's Center for Mendelian Genomics and the Pierce lab (https://oculargenomics.meei.harvard.edu/labs/pierce-lab/lab-members/). Through a review of available evidence we were able to apply the following criteria: PM2, PM3, PP1, PP5. Based on this evidence we have classified this variant as Likely pathogenic. If you have any questions about the classification please reach out to the Pierce Lab. -

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 405 of the CLN3 protein (p.Arg405Trp). This variant is present in population databases (rs139842473, gnomAD 0.01%). This missense change has been observed in individuals with retinitis pigmentosa (PMID: 24154662, 26766544, 28041643, 28559085). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 418137). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt CLN3 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -

Variant summary: CLN3 c.1213C>T (p.Arg405Trp) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 7.2e-05 in 250418 control chromosomes (gnomAD). This frequency is not higher than expected for a pathogenic variant in CLN3 causing Juvenile Neuronal Ceroid-Lipofuscinosis (Juvenile Batten Disease) (0.0014), allowing no conclusion about variant significance. The variant, c.1213C>T, has been reported in the literature in multiple homozygous and compound heterozygous individuals affected with isolated (i.e. nonsyndromic) retinitis pigmentosa (e.g. Wang_2014, Weisschuh_2016, Haer-Wigman_2017, Smirnov_2021), as well as in at least two homozygous patients in whom the development of late neurological involvement was also reported, suggestive of Juvenile Neuronal Ceroid-Lipofuscinosis (JNCL; or Juvenile Batten Disease) (Kuper_2017). These data indicate that the variant is very likely to be associated with disease. At least one publication reports that the variant was associated with increased lymphocyte vacuolization in patient-derived peripheral blood samples; however, the degree of vacuolization was less pronounced than in samples derived from patients with more severe, classical CLN3 disease phenotypes (Kuper_2017). Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and cited the variant as Pathogenic (n=2), Likely pathogenic (n=3) or VUS (n=1). Based on the evidence outlined above, the variant was classified as pathogenic. -
