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 c.1599+4C>A intronic variant results from a C to A substitution 4 nucleotides after coding exon 13 in the PTPN11 gene. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will not have any significant effect on splicing. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This sequence change falls in intron 13 of the PTPN11 gene. It does not directly change the encoded amino acid sequence of the PTPN11 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs142606486, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with PTPN11-related conditions. ClinVar contains an entry for this variant (Variation ID: 488167). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
