Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2 PP2 BP4_Moderate

The NM_016169.4(SUFU):​c.26C>G​(p.Ala9Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A9V) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
• Consequence: SUFU NM_016169.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 3.09

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 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SUFU. . Gene score misZ 1.9341 (greater than the threshold 3.09). Trascript score misZ 3.1202 (greater than threshold 3.09). GenCC has associacion of gene with apraxia, ciliopathy, ocular motor apraxia, Cogan type, nevoid basal cell carcinoma syndrome, Joubert syndrome, Joubert syndrome 32, medulloblastoma.
• BP4: Computational evidence support a benign effect (MetaRNN=0.14200032).
