Acne Syndromes and Mosaicism

Biomedicines, 2021
Abnormal mosaicism is the coexistence of cells with at least two genotypes, by the time of birth, in an individual derived from a single zygote, which leads to a disease phenotype. Somatic mosaicism can be further categorized into segmental mosaicism and

Clinical and morphological correlates of embryonic mosaicism: a retrospective cohort study of 10,469 blastocysts in PGT-A cycles [PDF]

Frontiers in Endocrinology
BackgroundChromosomal mosaicism presents a significant clinical and diagnostic challenge in preimplantation genetic testing for aneuploidy (PGT-A) cycles. While the meiotic origins of uniform aneuploidy are well-established, the predictors and mechanisms

#365 : Characteristics of Embryo Mosaicism Detected Using Next-Generation Sequencing PGT-A

Fertility & Reproduction, 2023
Background and Aims: Chromosomal mosaicism may occur in minority of embryos. Their commonality and uncertainty made the embryo mosaic rates vary from center to center.

Systematic detection of mosaicism by using digital NGS reveals three new MEN1 mosaicisms

Endocrine Connections, 2022
Purpose: Mosaicism is a feature of several inherited tumor syndromes. Only a few cases of mosaicism have been described in multiple endocrine neoplasia type 1 (MEN1).

Revealing parental mosaicism: the hidden answer to the recurrence of apparent de novo variants

Human Genomics, 2023
Mosaicism refers to the presence of two or more populations of genetically distinct cells within an individual, all of which originate from a single zygote. Previous literature estimated the percentage of parental mosaicism ranged from 0.33 to 25.9%.

Dynamic nature of somatic chromosomal mosaicism, genetic-environmental interactions and therapeutic opportunities in disease and aging

Molecular Cytogenetics, 2020
Background Somatic chromosomal mosaicism is the presence of cell populations differing with respect to the chromosome complements (e.g. normal and abnormal) in an individual.

Detection of germline mosaicism in fathers of children with intellectual disability syndromes caused by de novo variants

Molecular Genetics & Genomic Medicine, 2022
Background De novo variants are a common cause to rare intellectual disability syndromes, associated with low recurrence risk. However, when such variants occur pre‐zygotically in parental germ cells, the recurrence risk might be higher.

The inconsistency between two major aneuploidy-screening platforms—single-nucleotide polymorphism array and next-generation sequencing—in the detection of embryo mosaicism

BMC Genomics, 2022
Background In preimplantation genetic testing for aneuploidy (PGT-A), appropriate evaluation of mosaic embryos is important because of the adverse implications of transferring embryos with high-level mosaicism or discarding those with low-level mosaicism.

Mosaicism in 22q11.2 Microdeletion Syndrome [PDF]

Journal of Clinical and Diagnostic Research, 2018
Introduction: Microdeletion syndrome is characterized by sub-microscopic chromosomal deletion smaller than 5 Million bp (5Mb) and frequently associated with multiple congenital anomalies.
