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]

LRRTM3 (HGNC:19410): (leucine rich repeat transmembrane neuronal 3) Involved in presynapse assembly. Acts upstream of or within positive regulation of amyloid-beta formation. Is active in glutamatergic synapse. [provided by Alliance of Genome Resources, Apr 2022]

LOC101928961 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.578 is higher than 0.05.
