RASopathy VCEP

The c.1187C>T (p.Thr396Met) variant in MAP2K2 is present in 0.017% (11/61632) non-Finnish European alleles in gnomAD. This variant has been identified in a patient with an alternate molecular basis for disease (BP5; SCV000699629.2). Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Thr396Met variant is uncertain. RASopathy-specific ACMG/AMP criteria applied (PMID:29493581): BP5.

BP5

7 month old male evaluated for Noonan Syndrome with a 20 gene RASopathy panel. Variant was identified along with pathogenic variant c.214G>T (p.Ala72Ser) in PTPN11 (VCV000013324.4) (Integrated Genetics ClinVar submission: VCV000279960.3).

BS1

.017% (11/61632) non-Finnish European alleles in gnomAD, doesn’t meet BS1
