Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 2P and 11B. PM2BP4_ModerateBP6_Very_StrongBP7

The NM_000455.5(STK11):​c.1225C>A​(p.Arg409=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000696 in 1,435,836 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. R409R) has been classified as Likely benign.

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, LabCorpFeb 12, 2021Variant summary: STK11 c.1225C>A alters a conserved nucleotide resulting in a synonymous change. 4/4 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant was absent in 194938 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. Co-occurrence with a pathogenic variant has been reported (BARD1 c.448C>T, p.Arg150Ter), providing supporting evidence for a benign role. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as benign. -
