The novel duplication HRAS c.186_206dup p.(Glu62_Arg68dup): clinical and functional aspects.

Abstract excerpt

Specific activating missense HRAS variants cause Costello syndrome (CS), a RASopathy with recognizable facial features. The majority of these dominant disease causing variants affect the glycine residues in position 12 or 13. A clinically suspected CS diagnosis can be confirmed through identification of a dominant pathogenic HRAS variant. A novel HRAS variant predicting p.(Glu62_Arg68dup) was identified in an...
