Summaries for Homocystinuria Due to Deficiency of N -Methylenetetrahydrofolate...

NIH Rare Diseases : 52 Homocystinuria due to MTHFR deficiency is a genetic condition that results from poor metabolism of folate (also called vitamin B9), due to a lack of working enzyme called MTHFR. The gene that tells our body how to make the enzyme is also called MTHFR . At least 40 rare MTHFR gene variants have been found in people with decreased or no working enzyme. Very common gene variants (C677T and A1298C) can cause some decrease in enzyme function. People with homocystinuria due to MTHFR deficiency tend to have two rare variants or sometimes a rare variant and a common variant. Very rarely people inherit a combination of three or four common variants from their parents (for example two C677T variants and two A1298C variants) and may also develop very high levels of homocystine in their body. Homocystinuria usually does not show symptoms in a newborn baby. If untreated, children show signs and symptoms of severe homocystinuria in infancy. Newborn screening in most states includes a screening test for homocystinuria so that newborn infants can be treated early in their lives. However, homocystinuria due to MTHFR variants can be milder, presenting in later childhood or in adulthood. Symptoms may include abnormal clotting, developmental delay , seizures , intellectual disability , and microcephaly . Severe homocystinuria can also be caused by gene variants in other genes besides MTHFR. For more information about other causes of homocystinuria, see the GARD page: https://rarediseases.info.nih.gov/diseases/10770/homocystinuria For more information on having two common MTHFR gene variants (specifically, C677T and A1298C) visit our page: MTHFR gene variant

MalaCards based summary : Homocystinuria Due to Deficiency of N -Methylenetetrahydrofolate Reductase Activity, also known as methylenetetrahydrofolate reductase deficiency, is related to homocysteinemia and homocystinuria, and has symptoms including seizures, muscle weakness and muscle spasticity. An important gene associated with Homocystinuria Due to Deficiency of N -Methylenetetrahydrofolate Reductase Activity is MTHFR (Methylenetetrahydrofolate Reductase), and among its related pathways/superpathways are Metabolism of water-soluble vitamins and cofactors and Folate Metabolism. Affiliated tissues include testes, brain and eye, and related phenotypes are global developmental delay and behavioral abnormality

OMIM : 56 Methylenetetrahydrofolate reductase deficiency is a common inborn error of folate metabolism. The phenotypic spectrum ranges from severe neurologic deterioration and early death to asymptomatic adults. In the classic form, both thermostable and thermolabile enzyme variants have been identified (Rosenblatt et al., 1992). (236250)

UniProtKB/Swiss-Prot : 73 Methylenetetrahydrofolate reductase deficiency: Autosomal recessive disorder with a wide range of features including homocysteinuria, homocysteinemia [MIM:603174], developmental delay, severe mental retardation, perinatal death, psychiatric disturbances, and later-onset neurodegenerative disorders.
