| Gene Variant Descriptions | NRAS H131R lies within the G domain of the Nras protein (PMID: 17384584). H131R has been identified in sequencing studies (PMID: 24755198, PMID: 22817889), but has not been biochemically characterized and therefore, its effect on Nras protein function is unknown (PubMed, Dec 2023). |
