Genetic Variant PTPN11:p.His293Gln (chr12-112477676-C-G) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 3P and 7B. PM1PP2BP4_ModerateBP6BS2

The NM_002834.5(PTPN11):c.879C>G(p.His293Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000267 in 1,612,894 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/23 in silico tools predict a benign outcome for this variant. 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. H293Y) has been classified as Uncertain significance. The gene PTPN11 is included in the ClinGen Criteria Specification Registry.

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

Specifications for PTPN11 are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Likely_benign. The variant received -4 ACMG points.

PM1

In a hotspot region, there are 9 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 15 uncertain in NM_002834.5

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 LEOPARD syndrome 1, metachondromatosis, Noonan syndrome with multiple lentigines, Noonan syndrome-like disorder with loose anagen hair, Noonan syndrome 1, cardiofaciocutaneous syndrome, Noonan syndrome, Costello syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.07594091).

BP6

Variant 12-112477676-C-G is Benign according to our data. Variant chr12-112477676-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 280250.

BS2

High AC in GnomAdExome4 at 40 AD gene.
