What is trisomy 16 called?

Trisomy 16 (T16) is the most commonly observed trisomy among spontaneous pregnancy losses and it is estimated to occur in 1 to 1.5% of all pregnancies.

Is trisomy 16 Down syndrome?

Three copies of a particular chromosome is called trisomy, e.g. Trisomy 21 or Down syndrome. Other important trisomies include trisomy 13, 16 and 18. One copy of a chromosome would be a monosomy, e.g. Turner syndrome 46,X which is caused by loss of one of the two X chromosomes.

How many chromosomes does trisomy 16 have?

We have two copies of each of the chromosomes (23 pairs), one inherited from the father and one inherited from the mother but someone with mosaic trisomy 16 (MT16) has some cells with a third chromosome 16, making 47 chromosomes in those cells.

What does chromosome 16 indicate?

Chromosome 16 contains thousands of genes. The role of these genes is to guide protein production, which impacts a variety of functions in the body. Unfortunately, many genetic conditions are related to problems with the genes on chromosome 16.

What is trisomy 16 the leading cause of?

It is the most common trisomy leading to miscarriage and the second most common chromosomal cause of it, closely following X-chromosome monosomy. About 6% of miscarriages have trisomy 16. Those mostly occur between 8 and 15 weeks after the last menstrual period.

What are the symptoms of trisomy 16?

Mosaic trisomy 16 is a rare chromosomal anomaly syndrome with a highly variable phenotype ranging from minor anomalies with normal development to intrauterine growth retardation, abnormal skin pigmentation, craniofacial and body asymmetry, cardiac (e.g. ventricular septal defect) and genital (e.g. hypospadias.

Can a baby live with trisomy 16?

Mosaic trisomy 16, a rare chromosomal disorder, is compatible with life, therefore a baby can be born alive. This happens when only some of the cells in the body contain the extra copy of chromosome 16. Some of the consequences include slow growth before birth.

What does the 16th chromosome control?

Chromosome 16 contains thousands of genes. The role of these genes is to guide protein production, which impacts a variety of functions in the body.
