Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 11P and 1B. PM1PM2PM5PP2PP3_StrongBP6

The NM_002834.5(PTPN11):c.1402A>T(p.Thr468Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely benign (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T468M) has been classified as Pathogenic.

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 made for transcript

Verdict is Pathogenic. Variant got 10 ACMG points.

PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 6 uncertain in NM_002834.5
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr12-112488466-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 13331.Status of the report is reviewed_by_expert_panel, 3 stars.
PP2
Missense variant where missense usually causes diseases, PTPN11
PP3
MetaRNN computational evidence supports a deleterious effect, 0.976
BP6
Variant 12-112488465-A-T is Benign according to our data. Variant chr12-112488465-A-T is described in ClinVar as [Likely_benign]. Clinvar id is 981534.Status of the report is no_assertion_criteria_provided, 0 stars.
