Description

Variant summary: STK11 c.723T>C alters a non-conserved nucleotide resulting in a synonymous change. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 368 fold above the estimated maximal expected allele frequency for a pathogenic variant in STK11 causing Peutz-Jeghers Syndrome phenotype (6.3e-06), strongly suggesting that the variant is a benign polymorphism found primarily in populations of East Asian origin. To our knowledge, no occurrence of c.723T>C in individuals affected with Peutz-Jeghers Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and all classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign.
