Variant summary

Our verdict is Benign. The variant received -16 ACMG points: 0P and 16B. BP4_StrongBP6_Very_StrongBS2

The NM_013266.4(CTNNA3):c.1603C>T(p.Arg535Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0123 in 1,614,046 control chromosomes in the GnomAD database, including 205 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R535H) has been classified as Uncertain significance.

Genes affected

CTNNA3 (HGNC:2511): (catenin alpha 3) This gene encodes a protein that belongs to the vinculin/alpha-catenin family. The encoded protein plays a role in cell-cell adhesion in muscle cells. Mutations in this gene are associated with arrhythmogenic right ventricular dysplasia, familial 13. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]
