Key facts

Discrete genetic variant
Simple variant
This term is used to report the unique identifier of the simple variant found in this study. The identifier may come from various sources, including NCBI's ClinVar and Ensembl. For example, the variant NM_014049.4(ACAD9)c.1249C>T (p.Arg417Cys) has the ClinVar ID 30880 and would be reported in OBX-5 as 30880^NM_014049.4(ACAD9):c.1249C>T (p.Arg417Cys)^ClinVar.
