LOINC display name : CES1 gene c.428G A Molgen Ql (Bld/Tiss);
LOINC long common name : CES1 gene c.428G A [Presence] in Blood or Tissue by Molecular genetics method;
LOINC short name : CES1 c.428G A Bld/T Ql;
LOINC description : The CES1 gene encodes carboxylesterase 1A1 (CES1A1), which is the key enzyme involved
in the first-pass metabolism of methylphenidate (Ritalin). Presence of the CES1 Gly143Glu
missense variant (c.428G A, [NCBI dbSNP ID: rs71647871]) results in decreased CES1A1
activity, which may lead to a higher than expected plasma concentration of methylphenidate
and increase the risk of side effects.;
