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]

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Aug 12, 2024	The c.107C>T (p.A36V) alteration is located in exon 1 (coding exon 1) of the SUFU gene. This alteration results from a C to T substitution at nucleotide position 107, causing the alanine (A) at amino acid position 36 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 36 of the SUFU protein (p.Ala36Val). This variant is present in population databases (rs566714720, gnomAD 0.003%). 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: 241079). 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 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. -
