Down syndrome can be found in Asians, I have 3 cases.
I do not think I know for achondroplasia among blacks, but I think it is often in them.
Although some diseases are more common in certain breeds, to the other races. It is a kind of globalization!
Although no racial factors, other factors that influence the expression of these conditions.
Advanced maternal age is a risk factor for the supply of trisomy 21 or Down syndrome. FYI, this is a prerequisite for why pregnant women receiving prenatal triple screen with gestational diabetes at the age of 18 weeks. Down syndrome occurs in about a 800 to 1000 births. To an equal number of boys and girls are affected. Less than 25 percent of cases of Down syndrome occur because of an extra chromosome in the sperm. Most cases occur from Down syndrome because of an extra chromosome 21 in the egg supplied by the mother. With increasing age of women (maternal age) increases the risk for a Down syndrome baby increases significantly. For example, at a young age, the risk is that of 4000 When the woman is 35 years, the risk increases to one in 400 and 40 years, the risk increases to one in 110 and 45 years, the risk is, in 35th
With achondroplasia, advanced paternal age is a significant risk factor.It is caused by a mutation of fibroblast growth factor receptor 3rd There is no difference in the distribution of race, sex, and meets once per 40,000 live births.
