Genes affected
CTNNA1 (HGNC:2509): (catenin alpha 1) This gene encodes a member of the catenin family of proteins that play an important role in cell adhesion process by connecting cadherins located on the plasma membrane to the actin filaments inside the cell. The encoded mechanosensing protein contains three vinculin homology domains and undergoes conformational changes in response to cytoskeletal tension, resulting in the reconfiguration of cadherin-actin filament connections. Certain mutations in this gene cause butterfly-shaped pigment dystrophy. [provided by RefSeq, May 2016]

Uncertain significance, criteria provided, single submitterclinical testingUniversity of Washington Department of Laboratory Medicine, University of WashingtonNov 20, 2015- -
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 12, 2024The c.1185G>A variant (also known as p.L395L), located in coding exon 8 of the CTNNA1 gene, results from a G to A substitution at nucleotide position 1185. This nucleotide substitution does not change the leucine at codon 395. This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration may result in the creation or strengthening of a novel splice acceptor site. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear. -
