Genes affected

CTNND1 (HGNC:2515): (catenin delta 1) This gene encodes a member of the Armadillo protein family, which function in adhesion between cells and signal transduction. Multiple translation initiation codons and alternative splicing result in many different isoforms being translated. Not all of the full-length natures of the described transcript variants have been determined. Read-through transcription also exists between this gene and the neighboring upstream thioredoxin-related transmembrane protein 2 (TMX2) gene. [provided by RefSeq, Dec 2010]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000322 (49/152190) while in subpopulation NFE AF= 0.000529 (36/68014). AF 95% confidence interval is 0.000392. There are 0 homozygotes in gnomad4. There are 20 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 49 AD gene.

Ambry Genetics

Feb 02, 2022

The c.202C>T (p.R68W) alteration is located in exon 4 (coding exon 2) of the CTNND1 gene. This alteration results from a C to T substitution at nucleotide position 202, causing the arginine (R) at amino acid position 68 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
