Review on Down Syndrome in Newly Born Babies

Pravallika S

ABSTRACT

Down syndrome is a chromosomal anomaly that occurs in about 1 out every 700 births. The risk of having a baby with the condition is greater in women who are older than 35. But the majority of babies with Down syndrome are born to mothers younger than 35 simply because younger women are more likely to have babies than older women. In Down syndrome, an inexplicable error in cell development results in 47 chromosomes (rather than the usual 46) and the extra gene material slightly changes the orderly development of the body and brain.
