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]

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 228 of the SQSTM1 protein (p.Pro228Leu). This variant is present in population databases (rs151191977, gnomAD 0.01%). This missense change has been observed in individual(s) with sporadic amyotrophic lateral sclerosis and with frontotemporal lobar degeneration (PMID: 22084127, 24486447, 24899140). ClinVar contains an entry for this variant (Variation ID: 475402). 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. -
