Genes affected

EPHB6 (HGNC:3396): (EPH receptor B6) This gene encodes a member of a family of transmembrane proteins that function as receptors for ephrin-B family proteins. Unlike other members of this family, the encoded protein does not contain a functional kinase domain. Activity of this protein can influence cell adhesion and migration. Expression of this gene is downregulated during tumor progression, suggesting that the protein may suppress tumor invasion and metastasis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

The c.494C>T (p.P165L) alteration is located in exon 7 (coding exon 3) of the EPHB6 gene. This alteration results from a C to T substitution at nucleotide position 494, causing the proline (P) at amino acid position 165 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
