Education. Dermatology is one of the most highly competitive medical fields, and requires several years of education and training. The first step is an undergraduate degree from a four-year college, including pre-medical courses in biology, organic chemistry, physics, and chemistry.
Diagnosing Down Syndrome. Down syndrome is typically diagnosed during pregnancy or shortly after birth. Learn about the screenings available and what they mean.
Down syndrome, also known as Trisomy 21, is caused by an extra whole number chromosome 21, resulting in 47, rather than the normal 46 chromosomes. According to the Centers for Disease Control and Prevention, approximately one in every 700 babies in the United States is born with Down syndrome, making Down syndrome the most common chromosomal condition. About 6,000 babies with Down syndrome are born in the United States each year. The cause of the extra chromosome is unknown. Maternal age is the only factor that has been linked to an increased chance of having a baby with Down syndrome. However, due to higher birth rates in younger women, 80% of children with Down syndrome are born to women under 35 years of age.
