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:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

c.1448-5C>T in intron 12 of PTPN11: This variant is not expected to have clinica l significance because a C>T change at this position does not diverge from the s plice consensus sequence and is therefore unlikely to impact splicing. It has be en identified in 2/16512 South Asian chromosomes by the Exome Aggregation Consor tium (ExAC, http://exac.broadinstitute.org; dbSNP rs554790621). -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: c.1448-5C>T in PTPN11 gene is an intronic change that involves a non-conserved nucleotide. 5/5 programs in Alamut indicate this variant to strengthen a canonical acceptor site, however no functional studies supporting these predictions were published at the time of evaluation. The variant is present in the control population datasets of ExAC and gnomAD at frequency of 0.00002 (2/121396 and 5/246180 chrs tested, respectively), exclusively in individuals of South Asian descent (0.00016; 2/16512 and 5/30782, chrs respectively). The observed individual frequencies exceed the maximum expected allele frequency for a pathogenic variant of 0.0000625, suggesting the variant is likely to be an ethnic polymorphism. The variant of interest has not, to our knowledge, been cited by published reports or reputable databases/clinical laboratories. Taking together the variant was classified as Likely Benign until more data become available. -

Ambry Genetics

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1448-5C>T intronic variant results from a C to T substitution 5 nucleotides upstream from coding exon 13 in the PTPN11 gene. This nucleotide position is poorly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will not have any significant effect on splicing. Based on the available evidence, the clinical significance of this variant remains unclear. -
