In a smaller number of cases, the syndrome is the result of uniparental disomy in which the maternal contribution to chromosome 15q is replicated, replacing the paternal contribution (Knoll, Nicholls, Magenis, & Graham, 1989).
Some 30 percent of cases occur when both chromosome 15s are inherited from the individual's mother, a condition called uniparental disomy or UPD.
Because of an error during sperm formation, each child inherited two chromosome 15 segments from the father and none from the mother, a rare condition called uniparental paternal disomy.
They also identify long contiguous stretches of homozygosity, which may suggest an increased likelihood for a recessive condition or uniparental disomy (UPD).
535) studied the association of exposure to polychlorinanted biphenyls (PCBs) and dichlorodiphenyldichloroethylene (p, p'-DDE) with sperm sex-chromosome disomy in a cross-sectional study of 192 men from subfertile couples.
They looked for sperm disomy, which occurs when sperm cells have an abnormal number of chromosomes.
About 70% of cases are caused by a paternal genetic deletion on chromosome 15 (15q11-13), while 25% are from a maternal uniparental disomy of chromosome 15.
In a complete molar pregnancy, both sets of chromosomes are from the father, a condition known as paternal uniparental disomy (UPD).
4) The selection of mature sperm that are capable of binding to the zona pellucida of oocytes and to hyaluronic acid (HA) receptors (4) characterized by low levels of DNA fragmentation (32, 85-86) reduced frequency of chromosomal disorders such as disomy and diploidy (4) and improved probability of success rates (87).
