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

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.84).

BP6

Variant 19-1220369-G-A is Benign according to our data. Variant chr19-1220369-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 127703.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000615 (89/1446234) while in subpopulation SAS AF = 0.00037 (31/83784). AF 95% confidence interval is 0.000267. There are 1 homozygotes in GnomAdExome4. There are 57 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAdExome4 at 89 AD gene.
