A founder mutation causing a severe methylenetetrahydrofolate reductase (MTHFR) deficiency in Bukharian Jews.
Methylenetetrahydrofolate reductase (MTHFR) deficiency is a rare autosomal recessive disorder. A novel homozygous MTHFR c.474A>T (p.G158G) mutation was detected in two unrelated children of Jewish Bukharian origin. This mutation generates an abnormal splicing and early termination codon. A carrier frequency of 1:39 (5/196) was determined among unrelated healthy Bukharian Jews. Given the disease...

متن کاملLong term treatment with betaine in methylenetetrahydrofolate reductase deficiency.
A girl aged 7.5 years with deficiency of 5,10-methylenetetrahydrofolate reductase was treated from early infancy with betaine, 3-6 g daily. She has slight microcephaly, moderate developmental delay, and impaired vision but there have been no obvious signs of folate deficiency. From 4 years of age, she developed an unexplained extreme increase in appetite and weight. Recent magnetic resonance im...
متن کاملBetaine for treatment of homocystinuria caused by methylenetetrahydrofolate reductase deficiency.

متن کاملSevere methylenetetrahydrofolate reductase deficiency: clinical clues to a potentially treatable cause of adult-onset hereditary spastic paraplegia.
IMPORTANCE Hereditary spastic paraplegia is a highly heterogeneous group of neurogenetic disorders with pure and complicated clinical phenotypes. No treatment is available for these disorders. We identified 2 unrelated families, each with 2 siblings with severe methylenetetrahydrofolate reductase (MTHFR) deficiency manifesting a complicated form of adult-onset hereditary spastic paraparesis par...
