Scientific Background

RASopathies are a group of rare genetic disorders affecting the RAS/MAPK pathway, a signaling pathway responsible for cellular processes such as proliferation, survival and metabolism and it is vital for normal development. RASopathies are one of the most known groups of malformation syndromes and they affect approximately 1 in 1,000 individuals.

 

Who is this test for?

This test is applicable for individuals with family history of RASopathies and related syndromes, as well as for infants with several malformation characteristics or developmental delays. Because a lot of times clinical symptoms and phenotypical characteristics overlap between syndromes, genetic testing can provide valuable information to the doctor to enable accurate diagnosis by confirming or excluding a suspected syndrome and improve prognosis. Genetic testing can also help the doctor evaluate the best management plan as well as inform the patient for recurrence-risk.
