Genes affected

EPHA3 (HGNC:3387): (EPH receptor A3) This gene belongs to the ephrin receptor subfamily of the protein-tyrosine kinase family. EPH and EPH-related receptors have been implicated in mediating developmental events, particularly in the nervous system. Receptors in the EPH subfamily typically have a single kinase domain and an extracellular region containing a Cys-rich domain and 2 fibronectin type III repeats. The ephrin receptors are divided into 2 groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands. This gene encodes a protein that binds ephrin-A ligands. Two alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

Oct 25, 2023

The c.1280C>T (p.A427V) alteration is located in exon 5 (coding exon 5) of the EPHA3 gene. This alteration results from a C to T substitution at nucleotide position 1280, causing the alanine (A) at amino acid position 427 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
