What type of inheritance is involved in spina bifida?

What type of inheritance is involved in spina bifida?

Multifactorial: Isolated spina bifida (myelomeningocele) is a neural tube defect along with anencephaly that exhibits multifactorial determination--a combination of many genes and in utero environmental factors that cross a threshold to produce the defect. A couple having a child with spina bifida or anencephaly has a ~2% risk for each future pregnancy, a risk decreased by preconception folic acid. ...Read more

What is spina bifida?

Spina Bifida: Spina bifida is a birth defect where the spine does not close around the spinal cord during development. This may be as small as a small gap between the 2 sides, with no buldging out of membranes or nerves, & no associated handicaps, to a large defect with part of the cord exposed outside the body, leading to paralysis and other neurological problems. Folic acid decreases the risk. ...Read more

Is spina bifida hereditary?

Studies show that : the incidence of neural tube defects (NTD's) like open Spina Bifida would decrease by 70% if all women took 0.4mg of Folic Acid daily from menarche to menopause. However, this dose does not prevent NTD's in offspring of women with variations in several genes involved in folate (folic acid) & homocysteine metabolism. There are also inheritable genetic causes of NTD's that are not related to folate (folic acid) metabolism. ...Read more

Studies show that the incidence of NTD's could decrease by as much as 70% if all women were to take a daily Folic Acid supplement from menarche to menopause. ...Read more

Later side afects of occult spina bifida?

Later side afects of occult spina bifida?

No: Spina bifida occulta results from failure of the two lamina of one vertebra to make a solid bony fusion. The defect is generally bisecting the spinous process vertically. No instability is present. No neurologic dysfunction is present because neural elements are not affected. But associated neurological problems which may be symptomatic are more common in association with spina bifida occulta. ...Read more

How many forms of spina bifida are there?

How many forms of spina bifida are there?

Many: Embryonic development involves progressive closure of the neuro cord which becomes the spine. This closure may be slightly incomplete ( occult) or remain a cyst (meningomyelocele) or remain completely open. In some the pelvis and anus do not develop properly. Nerves to bladder, bowel, and legs may only partially develop. The brain may not develop properly, and hydrocephalus may develop. ...Read more

How can occult spina bifida impact a persons life?

How can occult spina bifida impact a persons life?

No impact: Spina bifida occulta is manifested by a single defect: failure of the two laminae of a vertebra to achieve bony union with each other. Often times the spinous process is associated with one lamina. Rarely is the spinous process completely absent. The vertebra has normal strength, normal associated joints, ligaments, qnd disks plus no nerve root herniation or compression. Occult = symptom-free. ...Read more
