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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PP2

Missense variant in the PTPN11 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 131 curated pathogenic missense variants (we use a threshold of 10). The gene has 13 curated benign missense variants. Gene score misZ: 3.1293 (above the threshold of 3.09). Trascript score misZ: 4.9438 (above the threshold of 3.09). GenCC associations: The gene is linked to Costello syndrome, Noonan syndrome 1, Noonan syndrome, LEOPARD syndrome 1, cardiofaciocutaneous syndrome, Noonan syndrome with multiple lentigines, metachondromatosis.

BP6

Variant 12-112454594-C-T is Benign according to our data. Variant chr12-112454594-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 44609.

BS2

High AC in GnomAd4 at 5 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
