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 affects a donor splice site in intron 7 of the SQSTM1 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), however the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in SQSTM1 cause disease. For these reasons, this variant has been classified as Pathogenic. Studies have shown that disruption of this splice site is associated with altered splicing resulting in multiple RNA products leading to truncation of C-terminal protein domains (PMID: 26208961). ClinVar contains an entry for this variant (Variation ID: 8110). This variant is also known as A390X. Disruption of this splice site has been observed in individuals with autosomal dominant SQSTM1-related conditions (PMID: 12374763, 17129171, 23417734, 26208961). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs796051870, gnomAD 0.0009%). -
