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]

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpNov 09, 2017Variant summary: The STK11 c.972G>A (p.Pro324Pro) variant involves the alteration of a non-conserved nucleotide causing a synonymous change and 5/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may alter ESE binding. However, these predictions have yet to be confirmed by functional studies. This variant was found in 8/216018 (2 homozygotes) control chromosomes (gnomAD), predominantly observed in the South Asian subpopulation at a frequency of 0.00029 (8/27558, 2 homozygotes)). This frequency is about 46 times the estimated maximal expected allele frequency of a pathogenic STK11 variant (0.0000063), suggesting this is likely a benign polymorphism found primarily in the populations of South Asian origin. In addition, a clinical diagnostic laboratory classified this variant as likely benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications. Taken together, this variant is classified as benign. -
