Genes affected

ENSG00000254732 (HGNC:):

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]

TMX2-CTNND1 (HGNC:41992): (TMX2-CTNND1 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring TMX2 (thioredoxin-related transmembrane protein 2) and CTNND1 (catenin, cadherin-associated protein, delta 1) genes on chromosome 11. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is therefore unlikely to produce a protein product. [provided by RefSeq, Dec 2010]

BTBD18 (HGNC:37214): (BTB domain containing 18) Predicted to be involved in several processes, including male gamete generation; piRNA biosynthetic process; and positive regulation of transcription elongation from RNA polymerase II promoter. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.439 is higher than 0.05.
