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:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.624A>G (p.T208T) alteration is located in exon 5 (coding exon 5) of the PTPN11 gene. This alteration consists of a A to G substitution at nucleotide position 624. This nucleotide substitution does not change the amino acid at codon 208. However, this change occurs in the last nucleotide of Exon 5 (c.526_642) which makes it likely to have some effect on normal mRNA splicing. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
