The NM_000455.5(STK11):c.290+36G>T variant causes a intron change involving the alteration of a non-conserved nucleotide. The gene STK11 is a tumor suppressor gene (CancerMine: 168 TSG, 33 oncogene, 60 driver citations). The gene STK11 is a known oncogene (CancerMine: 168 TSG, 33 oncogene, 60 driver citations). The gene STK11 is a cancer driver gene (CancerMine: 168 TSG, 33 oncogene, 60 driver citations). The variant allele was found at a cumulative frequency of 0.246 (AC=384,650) in the gnomAD database across 1,561,928 control chromosomes, including 53,360 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.704. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/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]
