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]

Gorlin syndrome;C0025149:Medulloblastoma Uncertain:1

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

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. 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. ClinVar contains an entry for this variant (Variation ID: 583037). This variant has not been reported in the literature in individuals affected with SUFU-related conditions. This variant is present in population databases (rs749802616, gnomAD 0.003%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 364 of the SUFU protein (p.Arg364Gln). -

Hereditary cancer-predisposing syndrome Uncertain:1
Jul 25, 2024
Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.R364Q variant (also known as c.1091G>A), located in coding exon 9 of the SUFU gene, results from a G to A substitution at nucleotide position 1091. The arginine at codon 364 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
