Urticaria in monozygotic and dizygotic twins. [PDF]
J Allergy (Cairo), 2012 Aim. To identify risk factors for urticaria, to determine the relative proportion of the susceptibility to urticaria that is due to genetic factors in an adult clinical twin sample, and to further determine whether the genetic susceptibility to urticaria overlaps with the genetic susceptibility to atopic diseases. Methods.

Genetic modelling of dizygotic twinning in pedigrees of spontaneous dizygotic twins [PDF]
American Journal of Medical Genetics, 1996 The inheritance of spontaneous dizygotic (DZ) twinning was investigated in 1,422 three-generation pedigrees ascertained through mothers of spontaneous DZ proband twins. DZ twinning was modelled as a trait expressed only in women. The penetrance was modelled first as a parity independent and secondly as parity dependent.

Molar incisor hypomineralisation: current knowledge and practice
International Dental Journal, EarlyView., 2020 Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...
