Hemivertebra in Monozygotic Twins
Spine, 2001A case report.To report and discuss a case of thoracic hemivertebra in monozygotic twins.The etiology of congenital scoliosis remains unclear. Both a genetic basis and environmental influences have been postulated. A few isolated reports of discordant spinal anomalies in twins exist.Clinical examination and plain radiograph evaluation were performed on

Surgical Pathology Clinics, 2013
This article discusses pathologies found in monozygotic twinning. Detailed information is provided regarding the development during monozygotic twin formation: embryo development, twin-to-twin transfusion syndrome, acardiac twinning, vanishing twins, conjoined twins, and Beckwith-Weidmann syndrome twins.

Documenta Ophthalmologica, 1979
In a group of monozygotic twins, in which at least one of the pair squinted, strabismus was observed in both twins in only about half of the cases. Within the concordant group there was variation in the way in which the anomaly became manifest.

Achalasia in monozygotic twins
Digestive Diseases and Sciences, 1982The familial occurrence of achalasia has been previously recorded and a genetic origin for the disease has been postulated. We present the first case of achalasia in monozygotic twins and suggest that concordance for the disease is consistent with a genetic factor in the etiology of achalasia.

Monozygotic Twinning as a Congenital Defect and Congenital Defects in Monozygotic Twins
Fetal Diagnosis and Therapy, 1990The 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.

Monozygotic twinning and structural defects
The Journal of Pediatrics, 1979An excess of structural defects occurs in monozygotic twins compared in dizygotic twins or singletons. The excess is composed of three categories of defects. The first includes defects which are part of the MZ twinning, such as conjoined twins and some amorphous twins.

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.

Delayed Ovulation and Monozygotic Twinning
Acta geneticae medicae et gemellologiae, 1976Aiming to show that delayed ovulation may induce MZ twinning, follicular maturation was induced in the rabbit by a small quantity of Pregnant Mare Serum Gonadotropin (16 UI four times): coitus, which induces ovulation in the rabbit, was delayed 60 hours after the last injection.

MONOZYGOTIC AND DIZYGOTIC TWIN DIAGNOSIS
Annals of Human Genetics, 1955SummaryA method of estimating the probability of dizygotic and monozygotic twin pairs is described. Parent‐child and sib‐sib frequency tables for the ABO, MNS and Rhesus blood‐group systems and formulae for obtaining these tables for the P, Lutheran, Kell, Duffy, Kidd and non‐secretor (or Lewis) systems are given.Tables of the distribution of ...
