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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The SUFU c.1245C>T; p.Gly415Gly variant (rs144158469), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 413910). This variant is found predominantly in the Admixed American population with an allele frequency of 0.2% (76/35440 alleles) in the Genome Aggregation Database (v2.1.1). This is a synonymous variant and computational analyses (Alamut Visual Plus v.1.5.1) predict that this variant may impact splicing by creating a novel cryptic donor splice site. However, it is uncertain if this new splice site is utilized without functional mRNA studies. While the high population frequency suggests that this is likely a benign variant, given the lack of clinical and functional data, the significance of this variant is uncertain at this time. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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. -
