Hemivertebra in Monozygotic Twins

Spine, 2001
A 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

Monozygotic Twinning

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.

Achalasia in monozygotic twins

Digestive Diseases and Sciences, 1982
The 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, 2009
The 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 Twins with Apert Syndrome

The Cleft Palate Craniofacial Journal, 2008
Apert 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, 1986
ABSTRACTThis 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).
