How to prevent your fetus from developing a rare genetic disorder
A study published in The Journal of the American Medical Association found that patients with an unusually high rate of leukemia, which is a rare but fatal form of cancer, were at a greater risk of having their pregnancies terminated.
The authors wrote that the researchers had examined information from the National Birth Defects Prevention Registry, a database of about 2.5 million women who gave birth between 1995 and 2004.
They found that the patients with a particularly high incidence of leukemia were five times more likely to have a baby with the rare genetic defect, which affects about 1 in every 100,000 people in the United States.
They also found that, on average, these patients had a more than 40 percent chance of having the genetic condition.
The study was funded by the National Institutes of Health and was conducted by researchers at The Children’s Hospital of Philadelphia and The Perelman School of Medicine at the University of Pennsylvania.
Researchers say that this finding is the first evidence of an association between a genetic defect and an increased risk of miscarriage.
The researchers did not say why this is the case, but they suggest that it might be linked to the fact that these patients are more likely than the general population to have inherited a mutation that causes their leukemia.
The gene mutation is known as CCR5, which makes it more susceptible to cancerous cells.
When these cells get into contact with the cells of the fetus, they cause an abnormal form of DNA called methylation to occur, a process that allows the DNA to be copied into a different form.
When the abnormal methylation is transferred into the maternal tissue, it can trigger an abnormally high risk of the baby developing leukemia.
This risk increases with the mutation and is increased by a factor of 20 or 30 when the mutation is passed on to the next generation.
If the mutation occurs early in pregnancy, it is more likely that the baby will be diagnosed with the cancer.
If it is passed onto a child during a miscarriage, the risk of cancer increases by about 20 percent.
The results are important because the research could help to identify specific genetic disorders that are more common in certain populations, the researchers said.
The finding of a genetic link between miscarriages and leukemia is particularly important because it could help physicians identify those patients who might benefit from genetic screening for the disease, said Dr. Paul Hirsch, an endocrinologist at New York University and lead author of the study.
The findings come as the number of pregnancies that are terminated each year is increasing, according to a survey conducted by the Pew Research Center.
More than 1.5 billion pregnancies are terminated annually in the U.S., and the number is expected to reach 6.2 billion by 2025, according a U.N. report released last year.
This increase has led to a growing number of people with leukemia, the rare but deadly form of the disease.
The number of babies born with leukemia has more than doubled in the past 20 years, according the U,N.
The National Cancer Institute estimates that about 1.2 million people in America have leukemia.
