How can we Diagnose Albinism?

Albinism can be diagnosed merely by observation of major or total absence of pigmentation of the skin, hair and eyes.

Other tests to diagnose albinism include -

Genetic Testing -

Genetic testing is the most accurate way to diagnose albinism and its specific type. This is helpful in families with albinism and is useful for specific, isolated populations who carry the trait in them.

Eye Examination -

An ophthalmologist should perform a complete examination of the eye of an affected individual. An electroretinogram test should be done to determine vision problems in albinism.

Chemical Testing of Hair -

Chemical testing of hair also provides an easy confirmation of the diagnosis of albinism.

► Hairbulb pigmentation test- It can be used to identify carriers. It is done by incubating a piece of the person's hair in a solution of tyrosine, an amino acid the body uses to make melanin. If the hair turns dark, it means the hair is making melanin. Light hair means there is no melanin synthesis.

► Tyrosinase test- It is more precise than the hairbulb pigmentation test. It measures the rate at which hair converts tyrosine into another chemical (DOPA), which is then made into pigment.

Blood Test -

Recently, a blood test has been developed that can identify carriers of the gene for some types of albinism.

Prenatal Diagnosis Of Albinism-

Amniocentesis and chorionic villus sampling can also diagnose some types of albinism in pregnancy.

Yeah, in Biology, I learned things such as Punnet Squares. If 2 capital A’s are in the genotype [AA], then they are not albino. If 2 lowercase a’s are in their genotype (aa), then they will be. If it is one of each (Aa), then they will not be albino, but they can pass it on to their kids. You have aa. Someone without albinism in their family at all is AA. If you marry that dude, your child will be Aa (they will not show albinism, but they can pass it on to their kids. If they marry someone with AA, the child will have a 50% chance of AA and a 50% chance of Aa ). If you marry someone with albinism in their family (Aa [actually, they could be AA also, but it is unlikely {it all depends on the parents}]) then your child will have a 50% chance aa (full albino) and a 50% chance Aa (pass it on to their children). Hope that helps. For more info, Google Punnet Squares.

male cant pass any symptoms because, they are XY and only the X holds the phenotype. female are XX so they can pass the phenotype. also male that has it cant hide it, because there is only 1 X. the X holds the genes so female may get XA Xa and that hide the phenotype because there is another X with lower case a.

awesome Sunday, November 13, 2011

you can go to genetic counceling to see if your children have a chance of having albinism. its all in genetics.

Jboyismyfriend Tuesday, February 28, 2012

Yeah, just see 2 comments up [pink_y]. Or, just read what I commented here: Yeah, in Biology, I learned things such as Punnet Squares.

I have a new friend at school that has this. He is the sweetest boy ever and I swear he acts no different than any other teenage boy on this earth [: But I'm always afraid to talk to him about this stuff like asking him questions I basically pretend like I don't notice that he's a black kid that's white. So this was helpful

I am planning to marry a woman whose father has albinism. Will i my children have albinism if I marry that woman though she does not have albinism.

Jboyismyfriend Tuesday, February 28, 2012

No. You have a 1 in 4 chance, though, that you child will have Aa, in which they can pass it on to their children. Otherwise, they will be AA, where they have not albinism at all. I think I just commented on you before.
