Notes

rs10509305, also known as Glu608Asp or E608D, is a variant in the storkhead box 1 STOX1 gene. In and subsequent publications, it is reported that when fetuses are rs10509305(C;C), their mothers are likely to have pre-eclampsia and possibly also pregnancy-induced hypertension.

A;C

See the rs10509305 SNPedia page for discussion. This genotype represents a carrier for a variant that, if inherited in two copies by a fetus, is associated with causing pre-eclampsia in the mother.

C;C

Fetuses inheriting two copies of rs10509305(C) are reported to cause pre-eclampsia during their (mother's) pregnancy. There may also be a tendency towards pregnancy-induced hypertension.
