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]

The c.800G>A (p.R267H) alteration is located in exon 6 (coding exon 6) of the SQSTM1 gene. This alteration results from a G to A substitution at nucleotide position 800, causing the arginine (R) at amino acid position 267 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The SQSTM1 c.800G>A variant is predicted to result in the amino acid substitution p.Arg267His. To our knowledge, this variant has not been reported in the literature in individuals with SQSTM1-related disorders. An alternative variant at the same codon (p.Arg267Cys) has been reported together with a variant in the DAO gene in a patient with sporadic amyotrophic lateral sclerosis (Table S3, Liu et al. 2021. PubMed ID: 34275688). This variant is reported in 0.016% of alleles in individuals of South Asian 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 variant is present in population databases (rs149424705, gnomAD 0.02%). 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SQSTM1 protein function. ClinVar contains an entry for this variant (Variation ID: 475405). This variant has not been reported in the literature in individuals affected with SQSTM1-related conditions. This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 267 of the SQSTM1 protein (p.Arg267His). -
