My (now deceased) partner's daughter-in-law had outrageously high MSAFPs
in both her pregnancies (may have had 3) 0 up in that 15 MOM are. All
work ups negative - all babies normal.
I think we wondered if perhaps her liver just didn't have the enzyme for
maternal breakdown of the fetal AFP and thus such elevated levels.
