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 ...

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.

Copy number variation analysis of twin pairs discordant for cleft lip with or without cleft palate
International Journal of Immunopathology and Pharmacology, 2019 Non-syndromic cleft lip with or without cleft palate (nsCL/P) is a frequent orofacial malformation. The comparison of concordance rate observed in monozygotic and dizygotic twins supports high level of heritability and a strong genetic component. However,

Concordant Intestinal Atresia in Two Pairs of Monozygotic Twins
American Journal of Perinatology Reports, 2011 Intestinal atresia in both twins from the same pregnancy is very rare. Only seven pairs of twins have been described. The authors report on two cases of monozygotic twins with different types of intestinal atresia and clinical evolution.

Discordant renal progression of Fabry disease in male monozygotic twins: a case report
Frontiers in Genetics, 2023 Background: Fabry disease (FD) is a rare X-linked lysosomal storage disease caused by mutations in the GLA gene that encodes α-galactosidase A (α-GAL).

Genome Biology, 2021 Background Although the genomes of monozygotic twins are practically identical, their methylomes may evolve divergently throughout their lifetime as a consequence of factors such as the environment or aging. Particularly for young and healthy monozygotic

A Twin Study of Genetic Contributions to Hippocampal Morphology in Schizophrenia
Neurobiology of Disease, 2002 Our goal was to establish whether altered hippocampal morphology represents a trait marker for genetic vulnerability in schizophrenia. We outlined the hippocampi on high-resolution MR images obtained from matched samples of control and discordant ...

Indian twin registry: A gold mine for genetic studies
Asian Journal of Medical Sciences, 2023 Twins are a source of curiosity, both for the family and the scientific community. Genetic similarities between twins have been the preferred choice to study the heritability of traits.

“Identical” double parathyroid adenomas in monozygotic twins
Otolaryngology 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 ...
