Protein Effect | loss of function - predicted |
Gene Variant Descriptions | NRAS G75_E76insDSAMRDQYMRTG results in the insertion of 12 amino acids in the Nras protein between amino acids 75 and 76 (UniProt.org). G75_E76insDSAMRDQYMRTG results in increased immature myeloid cells in a zebrafish model (PMID: 38522505), and therefore, is predicted to lead to a loss of Nras protein function resulting in activation of downstream signaling. |
