(For more information on trisomy 15q25-qter, see the Causes section below.). Trisomy usually happens because the sperm or egg has an extra chromosome. Approximately one third of affected infants and children may also experience episodes of uncontrolled electrical disturbances in the brain (seizures). Mosaicism (where some cells of the body are different from others-there are at least two cell types) occurs when the extra chromosome is not passed on to all the cells created from the original cell; hence, the baby has some cells that have a trisomy with 47 chromosomes and some cells that are normal with 46 chromosomes.

Pairs of human chromosomes are numbered from 1 through 22, with an unequal 23rd pair of X and Y chromosomes for males and two X chromosomes for females. When your cells divide, your sex cells can copy abnormally, causing a trisomy. Individuals with trisomy 13 often have heart defects, brain or spinal cord abnormalities, very small or poorly developed eyes ( microphthalmia ), extra fingers or . However, individuals with fewer cells with the extra chromosome 15 tend to have fewer health issues and may live longer. 14-19 ).

In many cases, individuals with Chromosome 15, Distal Trisomy 15q also have genital abnormalities. When cells form in reproductive organs, they start from one fertilized cell (sperm in males, eggs in females), then go through cell division (meiosis), where one cell splits twice to create four cells. Enroll in databases to allow researchers from participating institutions to find you. 1987). New York, NY: Oxford University Press; 1990:90. While healthy babies have two copies of genetic material in the thirteenth chromosome. Chromosomal testing is necessary to confirm the specific chromosomal abnormality present.
