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]

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: PTPN11 c.526-17T>C alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00044 in 250878 control chromosomes, predominantly at a frequency of 0.0031 within the East Asian subpopulation in the gnomAD database. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 49 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 a benign polymorphism found primarily in populations of East Asian origin. To our knowledge, no occurrence of c.526-17T>C in individuals affected with Noonan Syndrome and Related Conditions and no experimental evidence demonstrating its impact on protein function have been reported. A ClinVar submission (evaluation after 2014) cites the variant as benign. Based on the evidence outlined above, the variant was classified as benign. -
