Somatic
mosaicism occurs when there is a spontaneous reversion mutation that can lead to a mixed chimerism of corrected and uncorrected bone marrow cells leading to stabilisation or correction of an FA patient's blood counts in the absence of any administered therapy.

ILVEN is a hamartoma that usually is congenital or presents in early childhood; presents with linear or whorled, hyperkeratotic papules and plaque in similar linear "line of Blaschko" patterns; and represents cutaneous
mosaicism.
Among the 66.7% of chromosomally abnormal 3PN embryos, all of them were 69, XXY, and 13.3% of them showed
mosaicism. From previous studies, it is known that aneuploidy and
mosaicism in 3PN embryos can still constitute "normal" developmental events, with an etiology as mentioned above, and not necessarily a consequence of the 3PN status.
The findings, demonstrating "age
mosaicism," were published in Cell Metabolism on June 6, 2019.
ILVEN is a hamartoma that usually is congenital or presents in early childhood; presents with linear or whorled, hyperkeratotic papules and plaque in similar linear "line of Blaschko" patterns; and represents cutaneous
mosaicism. It is often difficult to differentiate between lichen striatus and ILVEN; however, lichen striatus is not congenital, and is a self-limited condition.
Pallister-Killian mosaic syndrome (PKS), also termed Pallister-Killian syndrome, Pallister mosaic aneuploidy, tetrasomy 12p
mosaicism, isochromosome 12p syndrome, or Teschler-Nicola syndrome is a rare dysmorphic disorder caused by mosaic tetrasomy of the short arm of chromosome 12 (12p).
A wide phenotypic variability in mixed gonadal dysgenesis has been previously described, with unilateral testicular structures, due in part to isodicentric Y(p) (idicY(p))
mosaicism or the presence of SRY in early gonadal ontogenesis of Sertoli cells (22).
The variation, called aACAysomatic
mosaicism,aACAO could explain why neurons in the temporal lobe are the first to die in Alzheimer's, for example, and why dopaminergic neurons are the first to die in Parkinson's.
Genetic variability within an organism can come about due to fusion between distinct individuals (chimerism) and/or through the accumulation of mutations, resulting in genetic
mosaicism (Gill et al., 1995; Barki et at., 2002).
It may be inherited, or caused by genetic
mosaicism, chimerism, disease, or injury.
