Genes affected
CLN5 (HGNC:2076): (CLN5 intracellular trafficking protein) This gene is one of eight which have been associated with neuronal ceroid lipofuscinoses (NCL). Also referred to as Batten disease, NCL comprises a class of autosomal recessive, neurodegenerative disorders affecting children. The genes responsible likely encode proteins involved in the degradation of post-translationally modified proteins in lysosomes. The primary defect in NCL disorders is thought to be associated with lysosomal storage function.[provided by RefSeq, Oct 2008]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 14, 2023For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the CLN5 protein in which other variant(s) (p.Tyr392*) have been determined to be pathogenic (PMID: 9662406). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 1072711). This premature translational stop signal has been observed in individual(s) with neuronal ceroid lipofuscinosis (PMID: 23374165). This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change creates a premature translational stop signal (p.Trp379*) in the CLN5 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 29 amino acid(s) of the CLN5 protein. -
