Variant summary

Our verdict is Pathogenic. The variant received 19 ACMG points: 19P and 0B. PS3 PM1 PM2 PM5 PP3 PP5_Very_Strong

The NM_015559.3(SETBP1):​c.2612T>C​(p.Ile871Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,886 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000803494: PS3-Moderate => PS3 downgraded in strength to Moderate (PMID:28346496)." and additional evidence is available in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I871S) has been classified as Pathogenic.

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

Our verdict: Pathogenic. The variant received 19 ACMG points.

• PS3: PS3 evidence extracted from ClinVar submissions: SCV000803494: PS3-Moderate => PS3 downgraded in strength to Moderate (PMID:28346496).; SCV004046107: Functional studies have shown that this variant is associated with an increase in protein levels compared to wild type SETBP1 (PMID: 28346496).; SCV000322149: Published functional studies demonstrate that the I871T variant alters SETBP1 function in vitro (Acuna-Hidalgo et al., 2017; Makishima et al., 2013); SCV004709685: 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).
• PM1: In a hotspot region, there are 12 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_015559.3
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr18-44951952-T-G is described in ClinVar as Pathogenic. ClinVar VariationId is 441093.Status of the report is criteria_provided_single_submitter, 1 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.837
• PP5: Variant 18-44951952-T-C is Pathogenic according to our data. Variant chr18-44951952-T-C is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 1031.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
