Is that me or my twin? Lack of self-face recognition advantage in identical twins. [PDF]

PLoS ONE, 2015
Despite the increasing interest in twin studies and the stunning amount of research on face recognition, the ability of adult identical twins to discriminate their own faces from those of their co-twins has been scarcely investigated.

Transcriptome Profiling Reveals Differential Expression of Circadian Behavior Genes in Peripheral Blood of Monozygotic Twins Discordant for Parkinson’s Disease

Cells, 2022
Parkinson’s disease (PD) is one of the most common neurodegenerative diseases. Investigating individuals with the most identical genetic background is optimal for minimizing the genetic contribution to gene expression.

Isolated anorectal malformation with rectoperineal fistula in monozygotic twins

Journal of Pediatric Surgery Case Reports, 2019
Incidence of anorectal malformation (ARM) is reportedly 1 in approximately 2500–5000 live births. While its etiology remains elusive, most evidence indicates genetic factors to be the major cause.

Epigenetic supersimilarity of monozygotic twin pairs

Genome Biology, 2018
Background Monozygotic twins have long been studied to estimate heritability and explore epigenetic influences on phenotypic variation. The phenotypic and epigenetic similarities of monozygotic twins have been assumed to be largely due to their genetic ...

Twinning rate trend in a population sample from the city of São Paulo, Brazil

Genetics and Molecular Biology, 2003
A retrospective study was carried out on a sample consisting of 89,491 deliveries occurred from 1979 through 1998, in the city of São Paulo, SP, Brazil. These deliveries included 935 twin and 26 triplet births. The mean incidence per 1,000 deliveries was

Isolated imperforate anus in dizygotic twins

Journal of Pediatric Surgery Case Reports, 2023
The authors report an isolated imperforate anus case in a dizygotic twin, which is the first reported case in the literature, the other reported cases were in monozygotic twins.

The importance of separation-individuation process in the treatment course of a monozygotic twin pair concordant for anorexia nervosa: a case report

Psychiatry and Behavioral Sciences, 2017
Anorexia nervosa is a serious mental illness with marked morbidity and mortality. Twin studies on anorexia nervosa concluded that there was a higher concordance rate in monozygotic twins (56%) than in dizygotic twins (7%).

Twins and endocrinology

Indian Journal of Endocrinology and Metabolism, 2014
Twins are two independent babies delivered during the same pregnancy and are divided as monozygotic or dizygotic based on their origin. Dizygotic twins are similar to two siblings and have different genetic information.

Monochorionic diamniotic twins of discordant external genitalia with 45,X/46,XY mosaicism

Molecular Genetics & Genomic Medicine, 2020
Background Monozygotic twins with 45,X/46,XY mosaicism, discordant for phenotypic sex, are extremely rare. Methods This report describes the clinical findings of a rare case of 45,X/46,XY mosaicism in monozygotic twins with different external genitalia ...

Monozygotic twins discordant for homologous Robertsonian translocation trisomy 21 of 46, XX, + 21, der (21;21) (q10; q10) in a twin-to-twin transfusion syndrome, case report

BMC Pregnancy and Childbirth, 2021
Background Monozygotic twins are nearly identical in genotype and phenotype because monozygotic twins arise from one fertilized oocyte. In all cases of discordant karyotype in monozygotic twins, trisomy 21 accounts for about one in 385,000.
