Targeted gene(s)/phenotype under study

Gene: CTNNA3 gene (OMIM 607667)


CTNNA3 gene is located on long arm of chromosome 10 and it encodes a protein that belong to the vinculin/alpha-catenin family. This protein plays a role in cell-cell adhesion. Microdeletions in this gene may are associated with arrhythmogenic right ventricular dysplasia 13, autism spectrum disorder and multiple fetal anomalies.

The echography controls in a pregnant were suggestive for duodenal stenosis, a genetic analysis was performed and it identified a microdeletion in CTNNA3.

Microdeletions in CTNNA3 gene are poorly reported in the literature. Therefore, the aim of this study is to collect clinical data on additional patients with a CTNNA3 microdeletion and to better describe the clinical features of this specific mutation.
