People with Down syndrome, a chromosomal disorder; around us, on the road or on social media. We are already used to seeing it. But when you think about it, all the people with Down syndrome we see are white.
Then why do we never see a black person with Down syndrome? Don’t their race and genetics predispose them to developing Down syndrome? Never? black with Down syndrome No?
First, let’s briefly define Down syndrome.
Chromosomes, the smallest gene packages in our body; as your baby develops during pregnancy and after birth how your body will form and function determines.
Typical people have 46 chromosomes, but people with Down syndrome are born with an extra chromosome called ‘chromosome 21’. Chromosome 21, hun that influence the development of the brain and body It also negatively changes mental and behavioral skills.
Does Down Syndrome discriminate between races?
Down syndrome occurs in all ethnic groups, regardless of race, but scientific and statistical research has shown that this syndrome is more common may vary slightly between different ethnic groups to point.
Even culture can influence the incidence of Down syndrome.
The age of the mother can even change the risk of the syndrome in the unborn baby. The age of the mother is not young, It can increase the risk of Down syndrome.
Therefore, the frequency of the syndrome varies in different ethnic groups depending on the age of the mothers. varies by ethnic group It can be based.
In other words, the differences in the syndrome according to ethnic groups are not actually due to gene differences.
Contrary to what we think, Down syndrome is almost equally common in white and black people. Our geography and environment is largely made up of white people and Down syndrome is not a common syndrome anyway. We don’t see black people with Down syndrome. It could be the cause.
In addition, black babies with Down syndrome are statistically less likely to die after the first year of life than white babies. chances of survival are smaller. The average level of care given to white women during pregnancy and birth may be higher than that given to black women. This socio-economic factor and racism may also cause fewer babies to be born with Black Down syndrome than white babies.
