| Impact List | indel |
| Protein Effect | unknown |
| Gene Variant Descriptions | PIK3CA G463_N465delinsD results in the deletion of three amino acids in the C2 PI3K-type domain of the Pik3ca protein from amino acids 463 to 465, combined with the insertion of an aspartic acid (D) at the same site (UniProt.org). G463_N465delinsD has not been characterized and therefore, its effect on Pik3ca protein function is unknown (PubMed, May 2026). |
