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]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.884
• PP5: Variant 10-102592654-A-G is Pathogenic according to our data. Variant chr10-102592654-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 446157.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr10-102592654-A-G is described in Lovd as [Pathogenic].
