What is trisomy 16 syndrome? Trisomy 16 is a chromosomal abnormality in which there are 3 copies of chromosome 16 rather than two. 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.
What are the symptoms of trisomy 16? Live-born infants with mosaic trisomy 16 have an average gestational age of 35.7 weeks with a birth weight near 2 SD below the average, and 93% live beyond the neonatal period.
What is the life expectancy of trisomy 16? Most cases of trisomy 16 result from nondisjunction in maternal meiosis I, which usually results in a first-trimester loss. If a trisomy 16 fetus is diagnosed on chorionic villus sampling or amniocentesis, then it is due to mosaicism in which one of the trisomic chromosomes is lost in mitotic cell division.
What causes trisomy 16 syndrome? 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, …
