The NM_016169.4(SUFU):c.1015C>T(p.Arg339Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,613,952 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R339Q) has been classified as Uncertain significance.

Gorlin syndrome;C0025149:Medulloblastoma Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 30, 2023 | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 339 of the SUFU protein (p.Arg339Trp). This variant is present in population databases (rs773037813, gnomAD 0.01%). 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: 241078). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SUFU protein function. 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. - |

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 23, 2021 | The c.1015C>T (p.R339W) alteration is located in exon 8 (coding exon 8) of the SUFU gene. This alteration results from a C to T substitution at nucleotide position 1015, causing the arginine (R) at amino acid position 339 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
