Diagnosis; Pre-symptomatic; Therapeutic management
Target population: Help
The Invitae Methylmalonic Acidemia and Homocystinuria Panel analyzes genes that are associated with elevations of methylmalonic acid and/or homocysteine. This test is useful for the diagnosis of patients who are suspected to have methylmalonic aciduria, homocystinuria, or combined defects of cobalamin metabolism based on clinical symptoms, biochemical findings, or abnormal … View more
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Invitae's variant interpretation methodology adheres closely to ACMG guidelines. Observed variants are interpreted according to the framework of evidence recommended by these guidelines, based on evidence in peer-reviewed literature and Invitae's database. Our clinical report documents the evidence and logic supporting each variant interpretation to make it easy for the … View more

Are family members with defined clinical status recruited to assess significance of VUS without charge? Help
Yes.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
