“…It is important to point out that there are several familial forms of uterine structural abnormalities as well as the inherited combination of uterine and urinary tract structural anomalies [Nykiforuk, 1938;Polishuk and Ron, 1974;Kurtz et al, 1980;Biedel et al, 1984;Stone et al, 2000;Cho et al, 2005;Uliana et al, 2008] in which fetal deformation might be expected to occur secondary to maternal uterine constraint. As well, there are syndromes and chromosomal anomalies in which uterine structural anomalies are known to occur [Shanks, 1956;Reece et al, 1982;Stone et al, 2000;Puvabanditsin et al, 2003;Ramirez and Lammer, 2004;Cho et al, 2005;Forzano et al, 2005;Mohan et al, 2006;Uliana et al, 2008]. Two of the 33 cases in this series have a history suggestive of a genetic form of uterine anomaly in mother.…”
