Variant chr3-41224613-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PM5PP2PP3PP5

The ENST00000349496.11(CTNNB1):c.101G>A(p.Gly34Glu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic,other (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G34A) has been classified as Likely pathogenic.

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.

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

PM1

In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 5 uncertain in ENST00000349496.11

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr3-41224613-G-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 376390.Status of the report is no_assertion_criteria_provided, 0 stars.

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, 0.829

PP5

Variant 3-41224613-G-A is Pathogenic according to our data. Variant chr3-41224613-G-A is described in ClinVar as [Likely_pathogenic, other]. Clinvar id is 17584.Status of the report is no_assertion_criteria_provided, 0 stars.
