| Gene Variant Descriptions | ERBB3 (HER3) N126K lies within the extracellular domain of the Erbb3 (Her3) protein (UniProt.org). N126K has been identified in the scientific literature (PMID: 29963236, PMID: 27602491, PMID: 32632529), but has not been biochemically characterized and therefore, its effect on Erbb3 (Her3) protein function is unknown (PubMed, Jun 2026). |
