Epilepsy and chromosomal abnormalities

Epilepsy and chromosomal abnormalities

BACKGROUND Many chromosomal abnormalities are associated with Central Nervous System (CNS) malformations and other neurological alterations, among which seizures and epilepsy. Some of these show a peculiar epileptic and EEG pattern. We describe some epileptic syndromes frequently reported in chromosomal disorders. METHODS Detailed clinical assessment, electrophysiological studies, survey of t...

Association of Fetal and Parental Chromosomal Abnormalities with Congenital Anomalies

Background & Aims: Chromosome abnormalities are a major cause of miscarriage and neonatal mortality. The present study aimed to determine the association of fetal and parents chromosomal abnormalities with congenital anomalies. Methods: A cross-sectional study was performed in a tertiary referral center (Afzalipour Hospital) over 16 months period (2011-2012). The study groups consisted of 77 fe...

Multi-institutional study on the correlation between chromosomal abnormalities and epilepsy.

While there is an abundance of literature describing the association of chromosome aberrations with epilepsy, only a few refer to the detailed features of epilepsy. It is important to investigate the associations between specific chromosome abnormalities and features of epilepsy to identify genes involved in epilepsy and treat them more effectively. We investigated the correlation between speci...

Chromosomal Abnormalities in Reimplantation Development

Direct testing of the outcome of human female meiosis demonstrated that up over a half of oocytes from IVF patients of advanced reproductive age are aneuploid, originating comparably from meiosis I and meiosis II errors, with potential probability of aneuploidy rescue in an almost half of oocytes with sequential first and second meiotic errors. One fifth of abnormalities originating from meiosi...
