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]

This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 22 of the CLN5 protein (p.Arg22Leu). This variant is present in population databases (rs576642281, gnomAD 0.03%). This missense change has been observed in individual(s) with clinical features of spastic ataxia (PMID: 29482223). ClinVar contains an entry for this variant (Variation ID: 409276). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
