CYP2C19*38 is assigned normal function based on definitive evidence. CYP2C19*38 was originally catalogued as CYP2C19*1.001 (i.e. CYP2C19*1A) (2009263). Due to the standardized nomenclature system this allele received its own star designation and is now catalogued as CYP2C19*38 (32602114). Therefore, because CYP2C19*38 does not contain any single nucleotide polymorphisms and the new star designation was a result of nomenclature standardization, consensus among experts was normal function.
