Genes affected

SETBP1 (HGNC:15573): (SET binding protein 1) This gene encodes a protein which contains a several motifs including a ski homology region and a SET-binding region in addition to three nuclear localization signals. The encoded protein has been shown to bind the SET nuclear oncogene which is involved in DNA replication. Mutations in this gene are associated with Schinzel-Giedion midface retraction syndrome. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

This variant is interpreted as a Pathogenic, for Schinzel-Giedion midface retraction syndrome, in Autosomal Dominant manner. The following ACMG Tag(s) were applied: PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PS2 => De novo (paternity and maternity confirmed) (PMID:20436468). PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PS4-Moderate => Recurrent mutation observed in multiple unrelated patients. (PMID:20436468,25028416). PS3-Moderate => PS3 downgraded in strength to Moderate (PMID:28346496). -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant has been previously reported as a de novo change in individuals with Schinzel-Giedion syndrome (SGS) (PMID: 28346496, 20436468, 22473152, 31680123). This variant is located in a 12-base pair hotspot region for pathogenic variation associated with SGS (PMID: 28346496). Functional studies have shown that this variant is associated with an increase in protein levels compared to wild type SETBP1 (PMID: 28346496). The c.2612T>C (p.Ile871Thr) variant is present in the heterozygous state in the gnomAD population database at a frequency of 0.0008% (2/251080). However, this gene may be prone to somatic variation (PMID: 34906245, 28346496) and it is not known if the variants observed in gnomAD represent germline or somatic events. This variant affects a highly conserved amino acid and is predicted by multiple in silico tools to have a deleterious effect on protein function. Analysis of the parental samples was negative for the variant, indicating this variant likely occurred as a de novo event. Based on the available evidence, c.2612T>C (p.Ile871Thr) is classified as Pathogenic. -

The SETBP1 c.2612T>C variant is predicted to result in the amino acid substitution p.Ile871Thr. This variant has been reported to occur de novo in more than 14 individuals with Schinzel-Giedion syndrome (Hoischen et al. 2010. PubMed ID: 20436468; Lestner et al. 2012. PubMed ID: 22473152; Miyake et al. 2015. PubMed ID: 25028416; Takeuchi et al. 2015. PubMed ID: 26096993; Acuna-Hidalgo et al. 2017. PubMed ID: 28346496). Functional studies suggested that the p.Ile871Thr variant confers increased protein stability, supporting the gain-of-function disease mechanism in Schinzel-Giedion syndrome (Acuna-Hidalgo et al. 2017. PubMed ID: 28346496). This variant is reported in 0.0018% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as pathogenic. -
