Variant summary
Our verdict is Benign. The variant received -17 ACMG points: 0P and 17B. BP4_StrongBP6_Very_StrongBP7BS2
The NM_000455.5(STK11):c.882G>A(p.Pro294Pro) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000121 in 1,565,228 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. P294P) has been classified as Likely benign.

Submissions by phenotype
Hereditary cancer-predisposing syndrome Benign:4
- -
- -
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
- -
Peutz-Jeghers syndrome Benign:4
- -
- -
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
- -
not specified Benign:3
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
- -
- -
STK11-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
Malignant tumor of breast Benign:1
The STK11 p.Pro294= variant was not identified in the literature nor was it identified in the MutDB, LOVD 3.0, Zhejiang Colon Cancer Database, Insight Hereditary Tumors Database. The variant was identified in dbSNP (ID: rs587781178) “With Likely benign allele,” ClinVar (as benign by GeneDx and likely benign by Ambry Genetics and Invitae), Clinvitae, and Cosmic databases. The variant was identified in control databases in 4 of 169630 chromosomes at a frequency of 0.000024 increasing the likelihood that this may be a low frequency benign variant in certain populations of origin (Genome Aggregation Consortium Feb 27, 2017). The p.Pro294= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
