MTHFR - Methylenetetrahydrofolate reductase (NAD(P)H) (rs1801133)
Die Methylentetrahydrofolat-Reduktase (MTHFR) ist an vielen Stoffwechselwegen im menschlichen Körper beteiligt. Im
Homocysteinstoffwechsel ist es für den Abbau von Homocystein zu Methionin verantwortlich. Der Polymorphismus rs1801133
führt zu einer verminderten, enzymatischen Aktivität der Methylentetrahydrofolat-Reduktase und somit zu einem erhöhten
Homozysteinspiegel.
