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]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BP6: Variant 5-179820798-G-C is Benign according to our data. Variant chr5-179820798-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 1214418.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0088 (1340/152276) while in subpopulation AFR AF= 0.0296 (1230/41568). AF 95% confidence interval is 0.0282. There are 17 homozygotes in gnomad4. There are 613 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck.
• BS2: High AC in GnomAd at 1337 AD gene.
