what are the effects of a consanguineous marriage?

Answer 1

Marrying a relative can lead to a much higher risk of having an affected child with an inherited disorder or disease. The risk and type of birth defects in consanguineous marriages varies according to how closely the couple is related. Most consanguineous couples can have normal healthy children. However, a couple in a consanguineous marriage should go for genetic counseling before attempting to conceive a baby so the risks to the fetus can be defined.

What should consanguineous couples look out for?
The most common defects are of the sense organs and the nervous system.
The skin colour may be pink and the hair white.
The eyes lack pigmentation - this is known as ocular Albinism.
Squint in children
Night blindness leading to Retinitis Pigmentosa
Photophobia, decreased visual acuity, moving eye and refractive errors
Hearing impairment. The great majority of hereditary deafness is caused by single autosomal recessive inheritance. The effect of consanguinity on hereditary deafness has been well studied and documented.

What are the diseases associated with consanguineous marriages?
Retinitis Pigmentosa is a hereditary degeneration and atrophy of the retina. It is usually progressive and leads to reduced peripheral vision that causes tunnel vision, night blindness and loss of vision. This disease affects children and young adults.

In Albinism there are defects in the pigmentation of the hair, skin and eyes. In ocular albinism, only the eyes are affected. This may be associated with photophobia (aversion to light), decreased visual acuity, nystagmus (constant jerky movement of the eyes) and refractive errors.

Anridia is a congenital condition where the iris is absent.

Coloboma of the iris/choroid is the absence of either of these structures, due to developmental abnormalities.

Answer 4

Depends on how close the relations are. Anything closer than first cousin is illegal in the USA. So, I will talk about first cousin marriage. There is a social stigma, and there may be family discord when first cousins marry.

Here are some quick and dirty facts:
"Children of non-related couples have a 2-3% risk of birth defects, as opposed to first cousins having a 4-6% risk."

"Current studies indicate that cousin couples have a lower ratio of miscarriages"

"We are all cousins. No two people are more distantly related than 50th cousins."

"No European country prohibits marriage between first cousins. It is also legal throughout Canada and Mexico to marry your cousin. The U.S. is the only western country with cousin marriage restrictions."

"Leviticus 18 lists all forbidden sexual relationships. Cousin relationships are not included."

Answer 5

I think that it would result in the loss of family, friends and one would have to deal with the stigma of marrying w/i the family. I would hope that this type of marriage would not result in any children. I really cant think of a more articulate way of saying that it is just icky....

Come to think of it, I think I may know of some people who are the result of a consanguineous union... not good

Answer 6

It's a criminal act in many countries and there is an increased risk of birth defects in children.

Though many would argue that all marriages are consanguineous because we all come from Adam and Eve.

Answer 7

Physical deformity, brain deformation etc., but I think it's almost impossible to marry an immediate relative in this day and age, blood tests are required for any legal marriage now.

Answer 8

I believe jail time as it is illegal in most states and any children born of this incestous union would have major risk of developmental delays.

Answer 9

Inbreeding causes bleeders, mentally deficient humans, problems too numerous to mention.

Answer 10

great marriages always have a time table of thing to come.
