Variant summary
Our verdict is Benign. Variant got -11 ACMG points: 0P and 11B. BP4_ModerateBP6BS1BS2
The NM_016169.4(SUFU):c.880G>A(p.Gly294Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000694 in 1,613,858 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. G294G) has been classified as Likely benign.

Uncertain significance, no assertion criteria provided | clinical testing | Genetic Services Laboratory, University of Chicago | Jun 29, 2022 | DNA 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 submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Apr 19, 2022 | Variant 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. - |
Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 04, 2023 | This 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. - |
