Genes affected

CTNNB1 (HGNC:2514): (catenin beta 1) The protein encoded by this gene is part of a complex of proteins that constitute adherens junctions (AJs). AJs are necessary for the creation and maintenance of epithelial cell layers by regulating cell growth and adhesion between cells. The encoded protein also anchors the actin cytoskeleton and may be responsible for transmitting the contact inhibition signal that causes cells to stop dividing once the epithelial sheet is complete. Finally, this protein binds to the product of the APC gene, which is mutated in adenomatous polyposis of the colon. Mutations in this gene are a cause of colorectal cancer (CRC), pilomatrixoma (PTR), medulloblastoma (MDB), and ovarian cancer. Alternative splicing results in multiple transcript variants.

CTNNB1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 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), CTNNB1. . Gene score misZ 3.846 (greater than the threshold 3.09). Trascript score misZ 5.712 (greater than threshold 3.09). GenCC has associacion of gene with severe intellectual disability-progressive spastic diplegia syndrome, exudative vitreoretinopathy, exudative vitreoretinopathy 7.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.833
• BS2: High AC in GnomAdExome4 at 5 AD gene.
