Scenario 2: Genetic Analysis Case Study on MAPK1 gene#

A Girl Diagnosed with Noonan-like Syndrome#

A girl was diagnosed affected by a Noonan-like syndrome, but she was negative after analysis of an extended panel for Rasopathies. Following Whole Exome Sequencing (WES), a de novo likely pathogenic mutation was found in the MAPK1 gene.


Research Questions#

Question 1: Mutation Prevalence#

Are there any other individuals with the same mutation or allelic variant?
