Description

Variant summary: PTPN11 c.214G>C (p.Ala72Pro) results in a non-conservative amino acid change located in the N-terminal Src homology 2 (N-SH2) domain of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251056 control chromosomes. c.214G>C has been reported in the literature in individuals affected with Noonan Syndrome (example, PMID: 18759865, 26918529). At least one publication reports experimental evidence evaluating an impact on protein function (example, PMID: 16358218). The most pronounced variant effect results in statistically significant higher phosphatase activities basally and after stimulation with BTAM peptide consistent with a gain of function mechanism of disease. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
