Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM1 PM2 PP2 PP5

The NM_002834.5(PTPN11):​c.348T>A​(p.His116Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000205 in 1,459,946 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H116N) 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

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PM1: In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_002834.5
• PM2: Very rare variant in population databases, with high coverage
• 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.
• PP5: Variant 12-112453210-T-A is Pathogenic according to our data. Variant chr12-112453210-T-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 503544.
