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]

ACMG classification

Verdict is Pathogenic. Variant got 18 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 18-44950744-TA-T is Pathogenic according to our data. Variant chr18-44950744-TA-T is described in ClinVar as [Pathogenic]. Clinvar id is 520830.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr18-44950744-TA-T is described in Lovd as [Pathogenic].

This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Met470*) in the SETBP1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SETBP1 are known to be pathogenic (PMID: 21037274, 25217958). This variant has not been reported in the literature in individuals affected with SETBP1-related conditions. For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 520830). -
