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]

SQSTM1 links:

MRNIP (HGNC:30817): (MRN complex interacting protein) Enables chromatin binding activity. Involved in several processes, including mitotic G2 DNA damage checkpoint signaling; regulation of double-strand break repair; and response to ionizing radiation. Located in nucleoplasm. Colocalizes with Mre11 complex. [provided by Alliance of Genome Resources, Apr 2022]

The SQSTM1 c.1177C>T variant is predicted to result in the amino acid substitution p.Arg393Trp. This variant was reported in an individual with Alzheimer disease (Table S2 in Wang et al. 2019. PubMed ID: 30954774). This variant is reported in 0.016% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/5-179263447-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 393 of the SQSTM1 protein (p.Arg393Trp). This variant is present in population databases (rs539942101, 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: 960129). 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 expected to disrupt SQSTM1 protein function with a positive 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. -
