Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM1 PM2 PM4_Supporting PP5_Moderate

The NM_000455.5(STK11):​c.856_858del​(p.Leu286del) variant causes a inframe deletion change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. L285L) has been classified as Likely benign.

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 Likely_pathogenic. Variant got 7 ACMG points.

• PM1: In a domain Protein kinase (size 260) in uniprot entity STK11_HUMAN there are 89 pathogenic changes around while only 17 benign (84%) in NM_000455.5
• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_000455.5. Strenght limited to Supporting due to length of the change: 1aa.
• PP5: Variant 19-1221330-CCTG-C is Pathogenic according to our data. Variant chr19-1221330-CCTG-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 374005.Status of the report is criteria_provided_single_submitter, 1 stars.
