Variant summary
Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BA1
This summary comes from the ClinGen Evidence Repository: The filtering allele frequency of the c.1650G>A (p.Ala550=) variant in the PTPN11 gene is 0.067% (13/11548) of Latino chromosomes by the Exome Aggregation Consortium, which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen RASopathy Expert Panel (BA1; PMID:29493581) LINK:https://erepo.genome.network/evrepo/ui/classification/CA292973/MONDO:0021060/004

ClinVar
Submissions by phenotype
not specified    Benign:2 
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. -
- -
RASopathy    Benign:2 
The filtering allele frequency of the c.1650G>A (p.Ala550=) variant in the PTPN11 gene is 0.067% (13/11548) of Latino chromosomes by the Exome Aggregation Consortium, which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen RASopathy Expert Panel (BA1; PMID:29493581) -
- -
Metachondromatosis    Benign:1 
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
LEOPARD syndrome 1    Benign:1 
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
PTPN11-related disorder    Benign:1 
This variant is classified as benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
Juvenile myelomonocytic leukemia;C0410530:Metachondromatosis;C4551484:LEOPARD syndrome 1;C4551602:Noonan syndrome 1    Benign:1 
- -
Cardiovascular phenotype    Benign:1 
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. -
