Genetic Variant PTPN11:p.Ser502Leu (chr12-112489081-C-T) – ACMG Classification: Pathogenic (19 pts)

Variant summary

Our verdict is Pathogenic. The variant received 19 ACMG points: 19P and 0B. PM1PM2PM5PP2PP3_StrongPP5_Very_Strong

The NM_002834.5(PTPN11):c.1505C>T(p.Ser502Leu) 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. 14/23 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S502P) has been classified as Uncertain significance.

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: Pathogenic. The variant received 19 ACMG points.

PM1

In a hotspot region, there are 21 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 13 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 chr12-112489080-T-G is described in ClinVar as Pathogenic. ClinVar VariationId is 40556.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

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.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.974

PP5

Variant 12-112489081-C-T is Pathogenic according to our data. Variant chr12-112489081-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 40557.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
