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]

Variant summary: The PTPN11 c.854-30T>C variant involves the alteration of a non-conserved intronic nucleotide and 5/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 4526/276876 control chromosomes (320 homozygotes) (gnomAD), predominantly observed in the Latino subpopulation at a frequency of 0.126476 (4349/34386). This frequency is about 2000 times the estimated maximal expected allele frequency of a pathogenic PTPN11 variant (0.0000625), suggesting this is likely a benign polymorphism found primarily in the populations of Latino origin. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. Taken together, this variant is classified as benign. -
