Genes affected
STK11 (HGNC:11389): (serine/threonine kinase 11) The protein encoded by this gene is a serine/threonine kinase that regulates cell polarity and energy metabolism and functions as a tumor suppressor. Mutations in this gene have been associated with the autosomal dominant Peutz-Jeghers syndrome, as well as with skin, pancreatic, and testicular cancers. [provided by RefSeq, May 2022]

Peutz-Jeghers syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Mar 15, 2017 | This sequence change inserts 8 nucleotides in exon 4 of the STK11 mRNA (c.525_532dupGGACATCA), causing a frameshift at codon 178. This creates a premature translational stop signal (p.Lys178Argfs*112) and is expected to result in an absent or disrupted protein product. While this particular variant has not been reported in the literature, loss-of-function variants in STK11 are known to be pathogenic (PMID: 15188174, 16287113). For these reasons, this variant has been classified as Pathogenic. - |
