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]

Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Aug 30, 2016 | In summary, donor and acceptor splice site variants are typically truncating (PMID: 16199547), and truncating variants in SUFU are known to be pathogenic (PMID: 22508808). However, without additional functional and/or genetic data, this variant has been classified as Likely Pathogenic. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a SUFU-related disease. This sequence change affects an acceptor splice site in intron 8 of the SUFU gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. - |
