• abnormality
  • He said the technique does not help with identifying the problem in all children, but there is a five to 12 percent chance that it will identify an abnormality in children with various disabilities where the previous chromosomal testing did not. (biologynews.net)
  • occur
  • However, when both parents contain matching chromosomal patterns, this obstacle does not occur. (wikipedia.org)
  • It is important to distinguish between chromosomal translocations occurring in gametogenesis, due to errors in meiosis, and translocations that occur in cellular division of somatic cells, due to errors in mitosis. (wikipedia.org)
  • found that rearrangements involving telomere regions are associated with chromosomal instability in human fibroblasts that occur many generations after exposure to accelerated heavy ions. (wikipedia.org)
  • haplogroup
  • In 2013, the discovery of a previously unknown Y-chromosomal haplogroup was announced, which resulted in a slight adjustment of the estimated age of the human Y-MRCA. (wikipedia.org)
  • Subsequent research using twelve Y-STR markers indicated that about half of contemporary Jewish Kohanim shared Y-chromosomal J1 M267, (specifically haplogroup J-P58, also called J1c3), while other Kohanim share a different ancestry, including haplogroup J2a (J-M410). (wikipedia.org)
  • Molecular phylogenetics research published in 2013 and 2016 for haplogroup J-M267 places the Y-chromosomal Aaron within subhaplogroup Z18271, age estimate 2638-3280 years Before Present (yBP). (wikipedia.org)
  • prenatal
  • A recent study published in the New England Journal of Medicine evaluated the accuracy and efficacy of chromosomal microarray as compared to karyotyping in prenatal diagnosis. (medindia.net)
  • clinical
  • They were explained the benefits and risks involved in the chromosomal microarray testing, including the fact that some of the findings could be of uncertain clinical significance. (medindia.net)
  • widely
  • Since the first edition, major advances and discoveries have made chromosomal mutagenesis a widely used technique and one that is available to any molecular biology laboratory, and this collection provides detailed protocols, case-studies, and reviews from thought-leaders in the field.

  • placenta
  • Confined placental mosaicism (CPM) represents a discrepancy between the chromosomal makeup of the cells in the placenta and the cells in the baby. (wikipedia.org)
  • Adam
  • As with "Mitochondrial Eve", the title of "Y-chromosomal Adam" is not permanently fixed to a single individual, but can advance over the course of human history as paternal lineages become extinct. (wikipedia.org)
  • Y-chromosomal data taken from a Neanderthal from El SidrĂ³n, Spain produced a Y-T-MRCA of 588,000 years ago for neanderthal and Homo sapiens patrilineages, dubbed ante Adam and 275,000 years ago for Y-MRCA. (wikipedia.org)

  • In fact, only a small fraction of the initial damage is transduction of late chromosomal damage has also been measured in the progeny of human lymphocytes that were exposed with much higher frequency in the progeny of cells that were exposed to heavy ions compared to gamma rays. (wikipedia.org)
  • test
  • Our baby died at 15 weeks and he was able to get some tissue to test for chromosomal issues and also hopefully we might know the sex of the baby. (dailystrength.org)
