Description

For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in STK11 are known to be pathogenic (PMID: 15188174, 16287113). This variant has been reported in individuals affected with Peutz–Jeghers syndrome (PMID: 9887330, 26979979). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Arg86*) in the STK11 gene. It is expected to result in an absent or disrupted protein product.
