Folate is especially important for people who are pregnant, as it aids in fetal development. If you dont get enough folate, complications such as anemia will be ongoing. Not all children with DS suffer from heart anomalies, which raises the question whether maternal factors might affect the risk of these anomalies. The production line hypothesis proposes that the order in which oocytes ovulate within a woman's reproductive life is determined by the order in which they were produced in utero 46. Applying one of the above risk curves 2 to maternal age distribution for England and Wales in 2002 23 yields prevalence of 1.89 per 1,000 births.

In humans, the excess of maternal over paternal remarriages in families with aneuploidy recurrence to different partners, is consistent with a cytoplasmic risk factor 3. It is possible to estimate the DS birth prevalence of a specific country, in the absence of prenatal diagnosis, by the average age-specific risk of an affected term pregnancy weighted by the proportion of maternities at each completed year of age. In addition, your baby may be premature (preterm birth) and/or have a low birth weight. With a concerted sustained effort large scale primary prevention may be realised in the near future.

This rate may not be applicable to women having prenatal diagnosis because of antenatal screening since they are younger, and extreme levels of the various screening markers are associated with non-viability. An association has been found between spontaneous abortions and a polymorphism, Pro259Arg, in the gene for transcobalimin, a protein that binds cobalamin and transports it to peripheral tissue 44.

For the most common genotype, a Robertsonian balanced translocation, if the mother is the carrier the recurrence risk is great enough to dwarf the agespecific risk at most ages, whilst in male carriers the risk is not high. And the frequency of euploidy is particularly uncommon when the parents have a balanced translocation, previous aneuploidy or advanced age. Moreover, the technique of PGD can be applied in order to achieve a normal pregnancy with the couples own gametes. Biochemical, molecular and epidemiological evidence suggests a link between DS and a defect in folate and methyl metabolism.
