| Protein Effect | gain of function - predicted |
| Gene Variant Descriptions | HRAS A146P lies within the SAK motif of the Hras protein (PMID: 24224811). A146P has not been characterized, but can be predicted to lead to a gain of Hras protein function and activation of downstream signaling based on the effects of HRAS A146T (PMID: 24224811, PMID: 21850009). |
