Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BA1BP4

This summary comes from the ClinGen Evidence Repository: The filtering allele frequency of the c.1658C>T (p.Thr553Met) variant in the PTPN11 gene (NM_002834.5(PTPN11):c.1658C>T (p.Thr553Met)) is 0.048% for European (Non-Finnish) chromosomes by the Exome Aggregation Consortium (49/66556 with 95% CI), which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen RASopathy Expert panel for autosomal dominant RASopathy variants (BA1). Computational prediction tools and conservation analysis suggest that the p.Thr553Met variant does not impact the protein (BP4). In summary, this variant meets criteria to be classified as benign. RASopathy-specific ACMG/AMP criteria applied: BA1, BP4 (Version 2.1; 09/17/2024). LINK:https://erepo.genome.network/evrepo/ui/classification/CA134644/MONDO:0021060/043

Genes affected
PTPN11 (HGNC:9644): (protein tyrosine phosphatase non-receptor type 11) The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains two tandem Src homology-2 domains, which function as phospho-tyrosine binding domains and mediate the interaction of this PTP with its substrates. This PTP is widely expressed in most tissues and plays a regulatory role in various cell signaling events that are important for a diversity of cell functions, such as mitogenic activation, metabolic control, transcription regulation, and cell migration. Mutations in this gene are a cause of Noonan syndrome as well as acute myeloid leukemia. [provided by RefSeq, Aug 2016]

Variant summary: PTPN11 c.1658C>T (p.Thr553Met) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00044 in 283484 control chromosomes. The observed variant frequency is approximately 7 fold of the estimated maximal expected allele frequency for a pathogenic variant in PTPN11 causing Noonan Syndrome And Related Conditions phenotype (6.3e-05), strongly suggesting that the variant is benign. Particularly in an elderly control population, this variant was found at allele frequency of 0.003 (3/1000 chromosomes), strongly supporting for a benign outcome (Beaudoin_2012). c.1658C>T has been reported in the literature including a fetus with clinical features of Noonan syndrome without information of clinical follow-up (Lee_2008), one patient with neurofibromatosis type 1 who also carried an NF1 splice site variant (Sant_2015), three patients with myocardial Infarction (Beaudoin_2012), one patient with breast cancer (Maxwell_2016), one patient with glioblastoma multiforme (Sturla_2011/TCGA database) and one lymphoid neoplasm sample (COSMIC/PMID: 22675565). However, none of the published studies provide strong evidence for or against pathogenicity. This variant has been identified by LMM laboratory in 5 individuals with clinical features of Noonan syndrome. However, it was also identified in 3 parents of unrelated probands who were reportedly unaffected (LMM unpublished data), strongly supporting for benign outcome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Multiple ClinVar submitters and one expert panel (ClinGen RASopathy Variant Curation Expert Panel) (evaluation after 2014) cite the variant as benign (n=4) and likely benign (n=10). Based on the evidence outlined above, the variant was classified as benign. -

p.Thr553Met in exon 14 of PTPN11: This variant has been reported in the literatu re in a fetus with increased nuchal translucency, which is a prenatal feature of Noonan syndrome. However, follow-up clinical information was not provided for t his fetus (Lee 2008). This variant has been identified by our laboratory in 5 in dividuals with clinical features of Noonan syndrome. However, it was also identi fied in 3 parents of unrelated probands in our laboratory who were reportedly un affected (LMM unpublished data). In addition, this variant has been identified i n 49/66556 European chromosomes by the Exome Aggregation Consortium (ExAC, http: //exac.broadinstitute.org; dbSNP rs148176616). Threonine (Thr) at position 553 i s not conserved in mammals or evolutionarily distant species, supporting that a change at this position may be tolerated. Additional computational prediction t ools do not provide strong support for or against an impact to the protein. In s ummary, the p.Thr553Met variant is classified as likely benign based on its pres ence in multiple unaffected individuals and lack of conservation. -

Computational prediction tools and conservation analysis suggest that the p.Thr553Met variant does not impact the protein (BP4). In summary, this variant meets criteria to be classified as benign.
