Monozygotic Twinning as a Congenital Defect and Congenital Defects in Monozygotic Twins
Fetal Diagnosis and Therapy, 2009The process of monozygotic twinning in animals and humans is presented. In addition, congenital defects in monozygotic twins versus dizygotic twins and singletons is discussed. Overall, the rates of congenital anomalies are higher among whites as compared to blacks, males as compared to females, and multiples as compared to singletons.

Endometriosis in monozygotic twins
Acta Obstetricia et Gynecologica Scandinavica, 1994Objective. To study the reproductive and medical history of monozygotic twin sisters and mothers of patients with endometriosis.Material and methods. Among 515 patients with endometriosis, eight had a monozygotic twin sister all of whom had had a gynecological laparoscopy or laparotomy. In addition, five of their mothers had had a laparotomy.

Monozygotic Twins with Apert Syndrome
The Cleft Palate Craniofacial Journal, 2008Apert syndrome results almost exclusively from one of two point mutations (Ser252Trp or Pro253Arg) in fibroblast growth factor receptor 2. Most patients with Apert syndrome have this as an autosomal dominant abnormality. The majority of cases are sporadic, resulting from new mutations.

Waldenström's Macroglobulinemia in Monozygotic Twins
Acta Medica Scandinavica, 1986ABSTRACTThis paper reports a unique familial occurrence of Waldenström's macroglobulinemia (WM) in monozygotic twins. The determination of twin monozygosity has been performed by electrophoretic and immunological typing of genetic systems (erythrocyte blood groups, leucocyte antigens and serum protein polymorphism).

Rett syndrome in monozygotic twins
American Journal of Medical Genetics, 1988AbstractThe evolution of the Rett syndrome in 29‐year‐old twin girls is presented. Evidence for monozygosity is given together with a brief account of the problems these girls posed to their family in early childhood.

1954
Publisher Summary Despite the fact that more than two decades have passed since Kronacher began his studies on cattle twins, no single test or series of tests yet exists through which it would be possible to distinguish between monozygotic and dizygotic cattle twins in an objective manner.

Assortative mating in monozygotic twins
Social Biology, 1990This study investigated assortative mating in a series of monozygotic twins in terms of anthropometric variables. Initially the twins were analyzed independent of each other, and the results showed fairly clear homogamy among female MZ twins and their spouses, after correcting for age.

Induction of monozygotic twinning in the mouse
Nature, 1978VINCRISTINE SULPHATE (Oncovin, Lilly) is a drug commonly used in the chemotherapy of acute leukaemias in children, lymphomas and certain other malignant conditions. We describe here experiments investigating the teratogenicity of this drug during the early stages of embryogenesis in the mouse.

Monozygotic Twins With Seizures
Archives of Neurology, 1991Eleven sets of monozygotic twins with idiopathic seizure disorders seen at Children's Hospital, Boston, Mass, were reviewed Nine twin pairs were concordant for seizures. A marked correlation in the precise timing of onset of seizures was found; three sets of twins had their first clinical seizures within a 24-hour period of one another.

Nasal Clearance in Monozygotic Twins
American Review of Respiratory Disease, 1974Abstract We studied nasal mucus flow rate in 12 nonsmoking pairs of monozygotic twins. A radioactivetagged particle was used to measure mucus flow rates at 4 different positions in the nose. A significant correlation was found between repeated measurements in the same subject, but the correlation between measurements within pairs was ...
