Description

This sequence change affects a donor splice site in intron 3 of the STK11 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in STK11 are known to be pathogenic (PMID: 15188174, 16287113). For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 1359873). Disruption of this splice site has been observed in individuals with Peutz-Jeghers syndrome (PMID: 30528796; Invitae). This variant is not present in population databases (gnomAD no frequency).
