Other treatments depend on the cause

Methionine synthase deficiency: high-methionine diet

Cystathionine synthase deficiency: Low-methionine, high-cysteine diet. Also, supplementation of vitamin B12 and folate (B9)

Impaired affinity of cystathionine synthase for pyridoxal phosphate: high-cysteine diet

MTHFR deficiency: folate (B9)
