Albinism is a congenital disorder that can be identified with amniocentesis during pregnancy or at birth. They have inherited altered genes that do not make the usual amounts of a pigment called melanin. One person in 17,000 in the U.S.A. has some type of albinism.
No, albinism is simply a lack of melanin production prior to birth and is spread through generations. Generally an albino baby will recieve albinism from the mothers father is the mothers father is albino.
Isn't it a defect in the melanon-producing cells of the skin?
yes sir it is
yes hemophilia can be detected before birth
Trisomy 18 can be detected before birth
There are no tests that can be done or can be diagnosed before birth.
Yes, it can be detected before birth. Doctors can use an ultrasound to determine if the child is homozygous dominant or heterozygous, in which cases the child would be infected with Achondroplasia, because it is a dominant trait.
Random orgasims, morning sickness and a fond for odd foods.
No it can not be detected so early, the girl must be 12 or14 years to have a breast to catch cancer, this is a disease of ladies not children.
By using a pedigree.
I think albinism still exists I have heard of some cases about it. Albinism is an inherited condition that is present at birth. Read more at: http://www.answers.com/topic/albinism == Albinism results from the inheritance of recessive alleles. The condition is known to affect mammals (including humans), fish, birds, reptiles and amphibians. The principal gene which results in albinism prevents the body from making the usual amounts of the pigment melanin. Most forms of albinism are the result of the biological inheritance of genetically recessive genes that are passed on from both parents, although some rare forms are inherited from only one parent.
albinism is common.
What are the demographics of albinism:
Ocular Albinism is a type of albinism that affects mostly vision. It commonly comes with the lack of melanin in the skin that occurs in regular albinism.
Not all birth defects are detected at birth, such as, for instance, Spina Bifida Occulta, a mild form of Spina Bifida which is often not detected until the person has an X-ray or other test that reveals the presence of the defect. But even that canbe detected at birth, if the child were to undergo such an X-ray or other test at that time. I know a person who was unaware that he had Spina Bifida Occulta until he had a spinal X-ray at the age of 65. Another common birth defect that sometimes is not detected at birth is a heart defect that causes a heart murmur, which may be detected later by a careful doctor while listening to the person's heart.
