| Gene Variant Descriptions | PIK3CA P104_V105del results in the deletion of two amino acids in the PI3K-ABD domain of the Pik3ca protein from amino acids 104 to 105 (UniProt.org). P104_V105del has been identified in sequencing studies (PMID: 28178681), but has not been biochemically characterized and therefore, its effect on Pik3ca protein function is unknown (PubMed, Feb 2025). |
