Associated with Noonan syndrome in OMIM and G2P (confirmed).

PMID: 31130282 (2019) - Six unrelated families with Noonan syndrome associated with heterozygous variants in the RRAS2 gene (5 de novo, 1 segregating variant in a family with four affected relatives). No other candidate variants were identified. Supporting functional data.

PMID: 31130285 (2019) - Three unrelated individuals with Noonan syndrome, harbouring de novo activating variants in the RRAS2 gene. Supporting functional analysis and zebrafish model.
