Translocation Abnormalities - a child gains an occur from multiple gene combinations additional chromosome through another route combined with environmental factors. e. g Down Syndrome Many childhood disorders tend to have higher - A piece of one chromosome attaches to another than usual incidence (heart disease, diabetes, chromosome. This can lead to conditions like Down Syndrome. cleft lip and palate, neural tube disorders) 4. Mosaicism down syndrome - an abnormal disorders is unpredictable condition when the nondisjunction disorder Do not follow the Mendelian Laws occurs after fertilization No set patterns in family history different cells in the body will have different chromosome counts. 6. IMPRINTING The extent of the disorder depends on the Imprinting - refers to the differential expression proportion of tissue with normal chromosome of genetic material and allows researchers to structure to tissue with abnormal chromosome identify chromosomal material has come from constitution. the male or female parent. - some genes work - This occurs when nondisjunction happens after differently depending on whether they come from your fertilization, leading to different cells in the body having mom or dad different chromosome counts. The severity depends on how many normal versus abnormal cells are present. CHROMOSOMAL ABNORMALITIES (CYTOGENIC DISORDERS) CHROMOSOMAL 5.
