Identical twins with “mirror image” anisometropia and esotropia [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo, 2011
Introduction. Identical twins account for 0.2% of the world population and 8% of all twins. A “mirror image” variation can be found in 25% of identical twins.

“Identical” double parathyroid adenomas in monozygotic twins

open access: yesOtolaryngology Case Reports, 2021
A number of genes have been associated with sporadic causes of primary hyperparathyroidism. A case of primary hyperparathyroidism secondary to simultaneously presenting double parathyroid adenomas with identical distribution in a set of 48-year-old ...

Ectodermal dysplasia in identical twins

open access: yesJournal of Pharmacy and Bioallied Sciences, 2013
Hereditary hypohidrotic ectodermal dysplasia (HED) is typically inherited as an X-linked recessive trait, characterized by deformity of at least two or more of the ectodermal structures - hair, teeth, nails and sweat glands.

Recognition of identical twins using fusion of various facial feature extractors

open access: yesEURASIP Journal on Image and Video Processing, 2017
Distinguishing identical twins using their face images is a challenge in biometrics. The goal of this study is to construct a biometric system that is able to give the correct matching decision for the recognition of identical twins.

Effects of smoking on genome-wide DNA methylation profiles: A study of discordant and concordant monozygotic twin pairs

open access: yeseLife, 2023
Background: Smoking-associated DNA methylation levels identified through epigenome-wide association studies (EWASs) are generally ascribed to smoking-reactive mechanisms, but the contribution of a shared genetic predisposition to smoking and DNA ...

Hippocampal Sclerosis in Identical Twins

open access: yesPediatric Neurology Briefs, 1998
The genetic and acquired hypotheses of etiology of hippocampal sclerosis (HS) were studied at the University of Melbourne, Australia, using quantitative MRI in three monozygous (MZ) twin pairs, only the index twin having temporal lobe epilepsy and HS.
