Clinical validity: Help
Noonan syndrome is caused by pathogenic/likely pathogenic variants in PTPN11(50% of clinically diagnosed patients), SOS1 (10%), KRAS (<5%), RAF1 (3%-17%), NRAS (1% or less), SHOC2 (1% or less), and RIT1 (5-10%). Costello syndrome is caused by pathogenic/likely pathogenic variants in HRAS (80%-90%) and KRAS(10%-15%). CFC syndrome is caused by pathogenic/likely … View more

Target population: Help
Individuals suspected of having a genetic disorder caused by a gene in the RAS pathway, e.g. Noonan syndrome, Costello syndrome, cardio-facio-cutaneous (CFC) syndrome, or multiple lentigines syndrome (LEOPARD syndrome).
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
VUS and novel variants will be interpreted by trained variant analysis team member and a lab director using the current ACMG variant classification criteria.

Are family members with defined clinical status recruited to assess significance of VUS without charge? Help
No.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
Yes. No systemic re-evaluation of previously reported variants/findings are currently performed. However, if the same variant/finding is identified in another patient and current assessment results in change in variant classification/interpretation, then the laboratory will recontact the ordering provider and issue an updated report.
