Genes affected

EPHA1 (HGNC:3385): (EPH receptor A1) 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 is expressed in some human cancer cell lines and has been implicated in carcinogenesis. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.73G>T (p.A25S) alteration is located in exon 1 (coding exon 1) of the EPHA1 gene. This alteration results from a G to T substitution at nucleotide position 73, causing the alanine (A) at amino acid position 25 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
