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]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant is located in the STK11 protein. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with STK11-related disorders in the literature. This variant has been identified in 2/267996 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
