Genes affected

RRAS (HGNC:10447): (RAS related) The protein encoded by this gene is a small GTPase involved in diverse processes including angiogenesis, vascular homeostasis and regeneration, cell adhesion, and neuronal axon guidance. Mutations in this gene are found in many invasive cancers. [provided by RefSeq, Jul 2015]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: The RRAS c.397G>A (p.Asp133Asn) variant involves the alteration of a conserved nucleotide, resulting in missense change. 2/4 in silico tools predict a benign outcome for this variant (SNPs&GO not captured due to low reliability index). This variant was found in 605/121088 control chromosomes (including one homozygote) from ExAC at a frequency of 0.0049964, which is approximately 1999 times the estimated maximal expected allele frequency of a pathogenic RRAS variant (0.0000025), suggesting this variant is likely a benign polymorphism. Taken together, this variant is classified as Benign. -
