Variant summary

Our verdict is Pathogenic. The variant received 22 ACMG points: 22P and 0B. PVS1 PS3 PM2 PP5_Very_Strong

The NM_016169.4(SUFU):​c.1022+1G>A variant causes a splice donor, intron change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,420 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 3/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000955383: Studies have shown that disruption of this splice site results in skipping of exon 8, and produces a non-functional protein and/or introduces a premature termination codon (PMID:12068298, 19533801" and additional evidence is available in ClinVar.

Genes affected

SUFU (HGNC:16466): (SUFU negative regulator of hedgehog signaling) The Hedgehog signaling pathway plays an important role in early human development. The pathway is a signaling cascade that plays a role in pattern formation and cellular proliferation during development. This gene encodes a negative regulator of the hedgehog signaling pathway. Defects in this gene are a cause of medulloblastoma. Alternative splicing results in multiple transcript variants.[provided by RefSeq, May 2010]

ACMG classification

Our verdict: Pathogenic. The variant received 22 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PS3: PS3 evidence extracted from ClinVar submissions: SCV000955383: Studies have shown that disruption of this splice site results in skipping of exon 8, and produces a non-functional protein and/or introduces a premature termination codon (PMID: 12068298, 19533801; Invitae).; SCV001451548: RT-PCR demonstrated this splice donor variant results in a protein lacking exon 8 and produces a frameshift which leads to an early stop codon and truncation of the protein (Pastorino et al. 2009). Co-precipitation studies showed this variant was unable to bind GLI1 and GLI2 transcription factors and accumulated with these transcription factors in the nucleus, thereby preventing suppression of hedgehog signaling pathway target genes (Taylor et al. 2002).
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-102599545-G-A is Pathogenic according to our data. Variant chr10-102599545-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 3571.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
