somatic mosaicism

  • Somatic mosaicism in FSHD often goes undetected. (
  • Pulsed-field gel electrophoresis-based studies show that mitotic mutations leading to somatic mosaicism occur equally frequently in patients and parents. (
  • Almost half of new FSHD mutations occur postfertilization, resulting in somatic mosaicism for D4Z4. (
  • GNAS and GPR101 mutations that arise in early embryonic age can lead to somatic mosaicism involving the pituitary gland and resulting in growth hormone excess. (


  • Examples of mosaicism are bilateral or anterior-posterior mosaic insects or mosaic birds, mottled leaves in plants, red and white facets in the compound eyes of insects, the presence of XX and XY cells in the same individual and other anomalies of certain chromosomal diseases of humans. (
  • Mosaicism (or mosaic Down syndrome) is diagnosed when there is a mixture of two types of cells, some containing the usual 46 chromosomes and some containing 47. (


  • An individual animal or plant may exhibit mosaicism, or it may occur in a culture of a single cell- or tissue-type obtained from an individual. (


  • Could anyone here give me some simple examples of imprinting and mosaicism? (


  • Chromosome nondisjunction is probably the principal cause of chromosomal aberration, which in turn may lead to the development of mosaicism. (


  • The occurrence of this process leads to mosaicism, mostly manifested as spots (clones of variant cells) on the cuticle of insects or on leaves, petals, or stamen hairs. (
