Mosaic trisomy 14 syndrome

Mosaic trisomy 14 syndrome, also called trisomy 14 mosaicism, is a rare chromosomal disorder in which some body cells carry three copies of chromosome 14, causing variable growth and developmental delay, heart defects, and body asymmetry.

Mosaic trisomy 15 syndrome

Mosaic trisomy 15 syndrome, also called mosaic trisomy chromosome 15, is a rare chromosomal disorder with an extra chromosome 15 in some cells, causing growth restriction, heart defects, and dysmorphism, with UPD15 and Prader–Willi risk.

Mosaic trisomy 16 syndrome

Mosaic trisomy 16 syndrome, a rare chromosomal anomaly (ORPHA:1708, ICD-10 Q92.1) where some cells carry an extra chromosome 16, causing variable growth restriction, cardiac and genital anomalies, with outcomes ranging from normal development to neonatal death.

Mosaic trisomy 17 syndrome

Mosaic trisomy 17 syndrome, also called trisomy 17 mosaicism, is an extremely rare chromosomal disorder with three copies of chromosome 17 in some cells, causing variable growth delay, intellectual disability, asymmetry, and heart defects; full trisomy 17 is lethal in utero.

Mosaic trisomy 2 syndrome

Mosaic trisomy 2 syndrome (trisomy 2 mosaicism, ORPHA:1723): rare chromosomal anomaly with extra chromosome 2 in some cells; IUGR, growth delay, craniofacial, heart, and neural tube defects; under 1 per million.

Mosaic trisomy 20 syndrome

Mosaic trisomy 20 syndrome (trisomy 20 mosaicism, ORPHA:1724): a rare chromosomal anomaly with an extra chromosome 20 in some cells; normal outcome in over 90% of prenatally detected cases, mild spinal, skin, and bowel features when present.

Mosaic trisomy 22 syndrome

Mosaic trisomy 22 syndrome is a rare chromosomal disorder in which some body cells carry an extra chromosome 22, causing growth delay, intellectual disability, and heart defects.

Mosaic trisomy 3 syndrome

Mosaic trisomy 3 syndrome, or trisomy 3 mosaicism (ORPHA:100071), is a rare chromosomal anomaly where some cells carry an extra chromosome 3, causing variable joint, facial, growth, and cardiac features; CVS findings are often confined placental mosaicism.

Mosaic trisomy 4 syndrome

Mosaic trisomy 4 syndrome (trisomy 4 mosaicism, ORPHA:96059) is an ultra-rare autosomal anomaly with an extra chromosome 4 in a fraction of cells, causing IUGR, heart defects, thumb aplasia, and pigmentation changes.

Mosaic trisomy 5 syndrome

Mosaic trisomy 5 syndrome (trisomy 5 mosaicism, ORPHA:96060) is an extremely rare chromosomal anomaly, fewer than 1 in 1,000,000, with a variable phenotype from normal to growth retardation, heart defects, and dysmorphism; only about seven cases reported.

Mosaic trisomy 7 syndrome

Mosaic trisomy 7 syndrome (trisomy 7 mosaicism, ORPHA:1747) is a rare chromosomal anomaly with a trisomic chromosome 7 cell line, causing Blaschko-line skin pigmentary dysplasia, asymmetry, growth delay, and sometimes maternal UPD 7 with Silver-Russell phenotype.

Mosaic trisomy 8 syndrome

Mosaic trisomy 8 syndrome, also called Warkany syndrome or trisomy 8 mosaicism, is a rare chromosomal disorder where some body cells carry three copies of chromosome 8.

Mosaic trisomy 9 syndrome

Mosaic trisomy 9 syndrome, also called trisomy 9 mosaicism, is a rare chromosomal disorder with some cells carrying an extra chromosome 9, causing intellectual disability, growth delay, heart, skeletal, and urogenital anomalies.

Mosaic variegated aneuploidy syndrome

Mosaic variegated aneuploidy (MVA) syndrome, also called Warburton-Anyane-Yeboa syndrome, is a rare autosomal recessive chromosomal-instability disorder with mosaic trisomies and monosomies in over 25% of cells, microcephaly, growth restriction, and childhood cancer risk, caused by BUB1B, CEP57, TRIP13, and related mitotic checkpoint genes.

Mosaicism

Mosaicism: two or more genetically distinct cell populations in one person, all from a single zygote, unlike chimerism. Covers postzygotic origins, germline versus somatic forms, PI3K/RAS pathway diseases, detection limits, and PGT-A embryo testing.

Mosasaur

Mosasaurs (Mosasauridae) were giant carnivorous marine squamates, or lizards, of the Late Cretaceous, named after Mosasaurus hoffmannii, first found at Maastricht in 1764; they gave live birth, ate other marine reptiles, and died out 66 million years ago.
