MTRR(redirected from methionine synthase reductase, mitochondrial)
MTRRA gene on chromosome 5p15.31 that encodes an enzyme involved in the reductive regeneration of cob(I)alamin cofactor required for maintaining methionine synthase in a functional state.
Defects in MTRR cause methylcobalamin deficiency type E and folate-sensitive neural tube defects.
