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]

Uncertain significance, no assertion criteria providedclinical testingGenetic Services Laboratory, University of ChicagoJun 29, 2022DNA sequence analysis of the SUFU gene demonstrated a sequence change, c.880G>A, in exon 7 that results in an amino acid change, p.Gly294Ser. This sequence change has been described in the gnomAD database with a frequency of 0.06% in the Latino/Admixed American subpopulation (dbSNP rs143807689). The p.Gly294Ser change affects a highly conserved amino acid residue located in a domain of the SUFU protein that is known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Gly294Ser substitution. This sequence change has been previously described in an individual with adrenocortical carcinoma (PMID: 26580448). Due to insufficient evidences and the lack of functional studies, the clinical significance of the p.Gly294Ser change remains unknown at this time. -
Likely benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpApr 19, 2022Variant summary: SUFU c.880G>A (p.Gly294Ser) results in a non-conservative amino acid change located in the Suppressor of fused C-terminal domain (IPR024314) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00013 in 251202 control chromosomes. The observed variant frequency is approximately 126 fold of the estimated maximal expected allele frequency for a pathogenic variant in SUFU causing Nevoid Basal Cell Carcinoma Syndrome (Gorlin Syndrome) phenotype (1e-06), strongly suggesting that the variant is benign. c.880G>A has been reported in the literature as a VUS of germline origin in an individual with adenocortical carcinoma from a cohort of individuals with pediatric cancer (example, Zhang_2015). However, this individual also harbored a pathogenic TP53 variant, c.1010G>A (p.Arg337His). These report(s) do not provide unequivocal conclusions about association of the variant with Nevoid Basal Cell Carcinoma Syndrome (Gorlin Syndrome). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as likely benign. -

Benign, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2023This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
