    Glossary Genetic Mosaicism

    presence of different genetic cell lines within one individual

    Genetic Mosaicism, also known simply as Mosaicism, refers to the presence of two or more genetically distinct cell lines within the same individual, originating from a single fertilized egg. This can result from mutations during cell division in early development, leading to some cells having different genetic makeup than others. This phenomenon can affect various tissues and organs, potentially leading to conditions like segmental vitiligo or certain forms of alopecia.
