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]

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.54).

BP6

Variant 19-1223081-G-A is Benign according to our data. Variant chr19-1223081-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 233233.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=0.181 with no splicing effect.

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.00000961 (14/1457018) while in subpopulation EAS AF = 0.000152 (6/39560). AF 95% confidence interval is 0.0000653. There are 0 homozygotes in GnomAdExome4. There are 5 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High AC in GnomAdExome4 at 14 AD gene.
