Genetic Normalization of Differentiating Aneuploid Human Embryos [PDF]

, 2011
Early embryogenesis involves a series of dynamic processes, many of which are currently not well described or understood. Aneuploidy and aneuploid mosaicism, a mixture of aneuploid and euploid cells within one embryo, in early embryonic development are ...

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

India's first child using PGT-M, PGT-A and HLA matching for helping a sibling having β-thalassemia major

Journal of Human Reproductive Sciences, 2019
β-thalassemia is a common single-gene disorder in India, with hematopoietic stem cell transplantation (HSCT) being the only cure. HSCT with matched unrelated donor is less successful, whereas finding a human leukocyte antigen (HLA)-matched related donor ...

Chromosomal disorders and male infertility [PDF]

, 2011
Infertility in humans is surprisingly common occurring in approximately 15% of the population wishing to start a family. Despite this, the molecular and genetic factors underlying the cause of infertility remain largely undiscovered.

The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos

Advanced Science, EarlyView.
Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

Patient Perspectives on Psychiatric Polygenic Risk Scores in Reproductive Decision‐Making and Polygenic Embryo Screening

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Polygenic risk scores (PRS) estimate individuals' genetic risk for developing multifactorial conditions. Recent genome‐wide association studies have enabled development of psychiatric PRS, which hold potential to streamline diagnosis and treatment of psychiatric conditions.

Preimplantation Genetic Testing of Multiple Endocrine Neoplasia Type 2A

Frontiers in Endocrinology, 2020
Background: When discussing matters of reproduction, the 2015 revised guidelines for the management of medullary thyroid carcinoma recommend that patients diagnosed with multiple endocrine neoplasia type 2A (MEN 2A) are informed about the option of ...
