not specified Benign:2
Variant summary: SUFU c.1291T>C alters a conserved nucleotide resulting in a synonymous change. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0015 in 277202 control chromosomes in the gnomAD database, including 4 homozygotes. The observed variant frequency is approximately 1489-folds higher than 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. To our knowledge, no occurrence of c.1291T>C in individuals affected with Nevoid Basal Cell Carcinoma Syndrome (Gorlin Syndrome) and no experimental evidence demonstrating its impact on protein function have been reported. Three ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cite the variant twice as benign and once as uncertain significance. Based on the evidence outlined above, the variant was classified as benign. -

Medulloblastoma Benign:1
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -
Hereditary cancer-predisposing syndrome Benign:1
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. -
