Rare Disease Mosaic Variation Identification

Mosaicism is the presence of two or more genomes in an individual that originated from a single zygote. Our company has extensive experience in rare disease target identification, especially in rare disease mosaic variation identification, and can provide you with professional services and customized research and development solutions, thereby revealing potential therapeutic targets and providing direction and higher efficiency for your rare disease drug research.

Overview of Mosaic Variation

Mosaicism is a common and unavoidable phenomenon in apparently normal individuals and contributes to the diversity of the human genome. Depending on the developmental stage at which the mutation occurs, mosaicism can be classified into one of three categories: i) somatic mosaicism, ii) germline mosaicism, or iii) gonosomal mosaicism, which is a combination of somatic and germline mosaicism. The type of mosaic variation and the particular stage of embryonic development at which the event occurs determine the outcome and severity of any given disease.

Advantages of NGS in Mosaic Variation Identification

The increasingly sensitive techniques available for variant discovery allow for more accurate identification of disease-causing variants. Recent studies have shown that next-generation sequencing (NGS) with deep sequence coverage has the potential to improve the sensitivity of detecting mosaic events and elucidating their role in rare diseases, including mosaic single nucleotide variants (SNVs), mosaic aneuploidy, and mosaicism in cancer. NGS allows the identification of low-level mosaicism that cannot be detected by traditional Sanger sequencing, which provides an in-depth understanding of the mosaic mutation spectrum and highlights the importance of genetic mosaicism as a rare disease mechanism.
