Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP6BS1
The NM_016169.4(SUFU):c.1027C>T(p.Arg343Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000335 in 1,614,030 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R343L) has been classified as Likely benign.

Gorlin syndrome;C0025149:Medulloblastoma    Uncertain:1 
This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 343 of the SUFU protein (p.Arg343Cys). This variant is present in population databases (rs751728820, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with SUFU-related conditions. ClinVar contains an entry for this variant (Variation ID: 406394). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SUFU protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Familial meningioma    Uncertain:1 
- -
Hereditary cancer-predisposing syndrome    Benign:1 
This alteration is classified as likely 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. -
