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 -16 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BP6: Variant 19-1220355-G-T is Benign according to our data. Variant chr19-1220355-G-T is described in ClinVar as [Likely_benign]. Clinvar id is 139332.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-1220355-G-T is described in Lovd as [Likely_benign].
• BS2: High AC in GnomAd at 8 AD gene.
