Protein Effect | loss of function - predicted |
Gene Variant Descriptions | PTEN N48I lies within the phosphatase tensin-type domain of the Pten protein (UniProt.org). N48I results in reduced phosphatase activity in a yeast assay (PMID: 29706350), and therefore, is predicted to lead to a loss of Pten protein function. |
