Description

For these reasons, this variant has been classified as Pathogenic. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Studies have shown that this variant results in partial deletion of exon 5 and introduces a premature termination codon (Invitae). The resulting mRNA is expected to undergo nonsense-mediated decay. This variant has been observed in individuals with Peutz-Jeghers syndrome (PMID: 9837816, 27721366; Invitae). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change falls in intron 5 of the STK11 gene. It does not directly change the encoded amino acid sequence of the STK11 protein. RNA analysis indicates that this variant induces altered splicing and may result in an absent or disrupted protein product.
