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]

Uncertain significance, no assertion criteria provided | clinical testing | Natera, Inc. | Oct 07, 2020 | - - |
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 01, 2022 | This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 45 of the CLN5 protein (p.Thr45Ile). This variant is present in population databases (rs768714949, gnomAD 0.009%). 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: 205140). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. - |
