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

This variant, c.714_716del, results in the deletion of 1 amino acid(s) of the SQSTM1 protein (p.Lys238del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs767056938, gnomAD 0.003%). This variant has been observed in individual(s) with amyotrophic lateral sclerosis and frontodemporal dementia (PMID: 22084127, 25114083). ClinVar contains an entry for this variant (Variation ID: 202213). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
