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]

Neuronal ceroid lipofuscinosis Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpApr 08, 2022This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 312 of the CLN5 protein (p.Ser312Asn). This variant is present in population databases (rs730882146, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with CLN5-related conditions. ClinVar contains an entry for this variant (Variation ID: 183049). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects CLN5 function (PMID: 25359263). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
