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]

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: 453977). This variant has not been reported in the literature in individuals affected with SUFU-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.009%). This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 250 of the SUFU protein (p.His250Gln). -

The p.H250Q variant (also known as c.750C>A), located in coding exon 6 of the SUFU gene, results from a C to A substitution at nucleotide position 750. The histidine at codon 250 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. -
