Disease

[C1TC_HUMAN] Defects in MTHFD1 may be a cause of susceptibility to folate-sensitive neural tube defects (FS-NTD) [MIM:601634]. The most common NTDs are open spina bifida (myelomeningocele) and anencephaly. Genetic defects in MTHFD1 may affect the risk of spina bifida via the maternal rather than the embryonic genotype.[1][2][3] Genetic variation in MTHFD1 could be associated with susceptibility to colorectal cancer (CRC) [MIM:114500].
