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]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant 19-1223021-A-G is Benign according to our data. Variant chr19-1223021-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 237807.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Likely_benign=7, Uncertain_significance=1}.
• BP7: Synonymous conserved (PhyloP=-0.611 with no splicing effect.
• BS2: High AC in GnomAdExome at 7 AD gene.
