Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2 PP3_Moderate

The NM_006270.5(RRAS):​c.175G>T​(p.Asp59Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,460,946 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D59H) has been classified as Uncertain significance.

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]

RRAS Gene-Disease associations (from GenCC):

• Noonan syndrome and Noonan-related syndrome

  Inheritance: AD Classification: STRONG Submitted by: G2P
• Noonan syndrome

  Inheritance: AD Classification: MODERATE, LIMITED Submitted by: ClinGen, Genomics England PanelApp
