Genes affected

SQSTM1 (HGNC:11280): (sequestosome 1) This gene encodes a multifunctional protein that binds ubiquitin and regulates activation of the nuclear factor kappa-B (NF-kB) signaling pathway. The protein functions as a scaffolding/adaptor protein in concert with TNF receptor-associated factor 6 to mediate activation of NF-kB in response to upstream signals. Alternatively spliced transcript variants encoding either the same or different isoforms have been identified for this gene. Mutations in this gene result in sporadic and familial Paget disease of bone. [provided by RefSeq, Mar 2009]

Collection Method:clinical testing

The c.352C>T (p.P118S) alteration is located in exon 3 (coding exon 3) of the SQSTM1 gene. This alteration results from a C to T substitution at nucleotide position 352, causing the proline (P) at amino acid position 118 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Review Status:no assertion criteria provided

Collection Method:clinical testing

The SQSTM1 c.352C>T variant is predicted to result in the amino acid substitution p.Pro118Ser. This variant has been reported in two individuals with amyotrophic lateral sclerosis (Scarlino et al. 2020. PubMed ID: 32397312; Table 2, van der Zee et al. 2014. PubMed ID: 24899140), but was also found in unaffected controls (van der Zee et al. 2014. PubMed ID: 24899140). It has also been reported in an individual with early-onset dementia (Table S2, Cuyvers et al. 2015. PubMed ID: 25796131). This variant is reported in 0.023% of alleles in individuals of European (non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 118 of the SQSTM1 protein (p.Pro118Ser). This variant is present in population databases (rs200152247, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with SQSTM1-related conditions. ClinVar contains an entry for this variant (Variation ID: 567262). 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 not expected to disrupt SQSTM1 protein function with a negative predictive value of 80%. 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. -
