The NM_002834.5(PTPN11):​c.1507G>C​(p.Gly503Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,866 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 14/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Pathogenic in Lovd. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G503E) has been classified as Pathogenic.

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]

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.001%). Predicted Consequence/Location: Inframe deletion located in a nonrepeat region: predicted to change the length of the protein and disrupt normal protein function. The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least 2 similarly affected unrelated individuals (PMID: 28117207). The variant has been reported at least twice as pathogenic without evidence for the classification (ClinVar ID: VCV000992499 /PMID: 28117207 /3billion dataset). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

The PTPN11 c.1507G>C; p.Gly503Arg variant (rs397507545) is reported in the literature in multiple individuals affected with Noonan syndrome and has been reported de novo in several (Chaves Rabelo 2022, Chinton 2019, Faggetter 2023, Hakami 2016, Matalon 2021, Mathus 2014, Sarkozy 2003). This variant is only observed on one allele in the Genome Aggregation Database, indicating it is not a common polymorphism. Computational analyses predict that this variant is deleterious (REVEL: 0.992). Based on available information, this variant is considered to be pathogenic. References: Chaves Rabelo N et al.

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 503 of the PTPN11 protein (p.Gly503Arg). This variant is present in population databases (rs397507545, gnomAD 0.004%). This missense change has been observed in individuals with Noonan syndrome or Leopard syndrome (PMID: 12717436, 12960218, 16358218, 18758896, 19077116, 19737548, 24754368). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 40558). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt PTPN11 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -

Variant summary: PTPN11 c.1507G>C (p.Gly503Arg) results in a non-conservative amino acid change located in the PTP type protein phosphatase domain (IPR000242) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 252092 control chromosomes. c.1507G>C has been reported in the literature in multiple individuals affected with Noonan Syndrome And Related Conditions, including a father and daughter showing co-segregation with disease (e.g. Zenker_2004, Tartaglia_2006, Lo_2008, Pierpont_2009, Mathur_2014, Bessis_2019, Chinton_2019). These data indicate that the variant is very likely to be associated with disease. Eight ClinVar submitters (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

The p.Gly503Arg (due to c.1507G>C or c.1507G>A) variant has previously been repo rted >10 individuals with the clinical features of Noonan syndrome, including at least 2 de novo occurrences (Tartaglia 2003, Sarkozy 2003, Zenker 2004, Kratz 2 005, Lo 2008, Ezquieta 2012, LMM data). This variant has also been reported in i ndividuals with Noonan syndrome and juvenile myelomonocytic leukemia (JMML), JMM L, and Noonan syndrome with Hodgkin?s lymphoma (Tartaglia 2003, Lo 2008). It ha s not been identified in large population studies. Three other variants involvin g this codon (p.Gly503Glu, p.Gly503Ala, p.Gly503Val) have been reported as patho genic. Computational prediction tools and conservation analysis suggest that the p.Gly503Arg variant may impact the protein. In summary, this variant meets crit eria to be classified as pathogenic for Noonan syndrome in an autosomal dominant manner. ACMG/AMP Criteria applied: PS4; PM1; PM2; PM6; PP3. -

The PTPN11 c.1507G>C variant is predicted to result in the amino acid substitution p.Gly503Arg. This variant is located in a mutational hotspot region of the PTPN11 gene. It has been repeatedly reported to be causative for Noonan syndrome (Sarkozy et al. 2003. PubMed ID: 12960218; Holmfeldt et al. 2013. PubMed ID: 23334668; Chinton et al. 2019. PubMed ID: 31560489). Additionally, a different variant, 1507G>A, that results in the same amino acid change has been reported as causative for Noonan syndrome (Tartaglia et al. 2006. PubMed ID: 16358218). At PreventionGenetics, we previously detected the variant c.1507G>C in other affected patients. This variant is reported in 0.0046% of alleles in individuals of European (Finnish) descent in gnomAD. This variant is interpreted as pathogenic. -

The p.G503R pathogenic mutation (also known as c.1507G>C), located in coding exon 13 of the PTPN11 gene, results from a G to C substitution at nucleotide position 1507. The glycine at codon 503 is replaced by arginine, an amino acid with dissimilar properties, and is located in the PTP domain of the PTPN11 protein. This mutation has been reported in multiple individuals with Noonan syndrome, including at least two affected parent-child pairs (Sarkozy A et al. J Med Genet, 2003 Sep;40:704-8; Lo FS et al. Int J Hematol, 2008 Oct;88:287-290; Bessis D et al. Br J Dermatol, 2019 06;180:1438-1448). The same amino acid substitution caused by a different nucleotide change (c.1507G>A) has also been reported in individuals with Noonan syndrome (Tartaglia M et al. Am J Hum Genet, 2006 Feb;78:279-90; Athota JP et al. BMC Med Genet, 2020 03;21:50). There have been reports of a few individuals with p.G503R and Noonan syndrome diagnosed with juvenile myelomonocytic leukemia (JMML) (Strullu M et al. J Med Genet, 2014 Oct;51:689-97; Kratz CP et al. Br J Cancer, 2015 Apr;112:1392-7). Based on internal structural analysis, this variant is more destabilizing than other nearby pathogenic variants (Hof P et al. Cell, 1998 Feb;92:441-50). In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation for PTPN11-related RASopathy; however, its clinical significance for metachondromatosis is uncertain. -
