The March of Dimes defines birth defects as "an abnormality of structure‚ function or body metabolism presenting at birth or early childhood that results in physical or mental disability‚ or is fatal." There are a couple of different contributors to genetic birth defects. Some birth defects stem from a

Multiple myeloma Multiple myeloma (also plasma cell myeloma also known as MM‚ myeloma‚ plasma cell myeloma‚ or as Kahler’s disease) is a progressive hematologic (blood) disease. It is a cancer of the plasma cell‚ an important part of the immune system that produces immunoglobulins (antibodies) to help fight infection and disease. The immune system is made up of several types of cells that work together to fight infections. Lymph cells (called lymphocytes) are the main type of cell in the adaptive

Other types of mutations are: point mutations‚ missense mutations‚ frameshift mutations and chromosomal abnormalities (“Section 8.1 Mutations‚” 2000). Part II 1.

Cerebral Palsy can be caused by numerous problems occurring in the prenatal period‚ prematurity‚ labor and delivery complication in the newborn period. Due to genetic or chromosomal abnormality to the brain may not develop in the typical way. Some environmental factors such as drugs metabolic problems and placental dysfunction may also lead to CP.

Turner Syndrome is defined by “a chromosomal condition that affects development in females. ” (“Turner Syndrome”). Turner Syndrome is caused by a chromosome abnormality. Normally‚ females will have two X chromosomes (XX) and males will have one X and one Y chromosome (XY) (Matthews). In Turner Syndrome‚ there is a defect in the X Chromosome. It is

Prenatal Development • In the life span development the shortest is the period of the newborn or infancy • This period‚ which begins at conception and ends at birth‚ is approximately 270 to 280 days in length or nine calendar months. • How life begins? o New life begins with the union of male sex cell and female sex cell. o These sex cells are developed in the reproductive organs‚ the gonads. o Male gonad is “testes” and female gonad is “ovaries” o Male sex cell is referred as “spermatozoon”
