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

Our verdict: Benign. The variant received -18 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.36).
• BP6: Variant 19-1207003-C-T is Benign according to our data. Variant chr19-1207003-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 184843.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000376 (55/1461456) while in subpopulation NFE AF = 0.0000459 (51/1111820). AF 95% confidence interval is 0.0000355. There are 0 homozygotes in GnomAdExome4. There are 27 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High AC in GnomAdExome4 at 55 AD gene.
