During human embryogenesis, neural crest cells migrate to the anterior chamber of the eye and then differentiate into the inner layers of the cornea, the iridocorneal angle, and the anterior portion of the iris. When proper development does not occur, this causes iridocorneal angle dysgenesis and intraocular pressure (IOP) elevation, which ultimately results in developmental glaucoma. Here, we ...

A non-fluorescent Y chromosome was observed in a phenotypic male with 45,X/46,XYq-mosaicism and mixed gonadal dysgenesis. Q-banding of the father's chromosomes showed a normally fluorescent Y. Measurements of the Y chromosomes in the father and the patient showed a significant difference in length. Evidence for translocation of the Y fluorescent segment to another chromosome was lacking in the ...

Strains of Drosophila melanogaster bearing the male recombination factor 23.5 MRF induce hybrid dysgenesis in a way which is highly reminiscent of the P-M system, and, most probably, causally related to the activity of the transposable element hobo. We have investigated potential interactions between the two systems of hybrid dysgenesis by studying mixed lines derived from bidirectional crosses...

Abstract Background Much interest has not been placed on the role of chromosomal abnormalities in pathogenesis and rising prevalence infertility recent times. This review was conducted to renew public basis infertility, testing, management. Main text Meiotic post-zygotic mitotic errors may cause infertility-predisposing abnormalities, including Klinefelter syndrome, Jacob Triple X Turner Down s...

P strains of Drosophila are distinguished from M strains by having P elements in their genomes and also by having the P cytotype, a maternally inherited condition that strongly represses P-element-induced hybrid dysgenesis. The P cytotype is associated with P elements inserted near the left telomere of the X chromosome. Repression by the telomeric P elements TP5 and TP6 is significantly enhance...

Cortical dysgenesis is increasingly recognised as a cause of epilepsy. We report a case with double cortex heterotopia and secondarily generalized seizures with a generalised spike wave pattern. During the course of the disease, the child developed electrical status epilepticus in slow wave sleep. From the first examination, sleep pattern revealed increased frequency and amplitude of spindle ac...
