  • Incidental findings according to ACMG recommendation

    Dear All,

    I have a question about how to report incidental findings in exome samples for the clinical diagnostic purposes.
    I have read the ACMG recommendations for reporting incidental findings in patients and tried to filter out the pathogenic variants in the 56 genes suggested to be checked by ACMG.
    When I filter out the variants using common polymorphisms in dbSNP142, the remaining pathogenic variants are mostly not so much. However, without this filtration there would be around 20 remaining variants on average that should be checked manually to investigate their probable pathogenicity.
    Most of these variants are the common polymorphisms (reported through GWAS studies) which are associated with more common disorders and not the rare variants of monogenic disorders.
    Since there is no accurate recommendation about the type of variants that should be reported to patients, I was wondering whether we should check these associated polymorphisms manually and investigate their effects in these disorders and then report them to patients, or we should just report the rare pathogenic variants (DM variants in HGMD) as incidental findings?

    I am looking forward to hearing from you.

    ACMG guidelines recommends to report "Mendelian type" variants not "GWAS type" variants. Pls read the guideline again

      A Brief Overview and Common Challenges in Single-cell Sequencing Analysis
      by seqadmin

      ​​​​​​The introduction of single-cell sequencing has advanced the ability to study cell-to-cell heterogeneity. Its use has improved our understanding of somatic mutations1, cell lineages2, cellular diversity and regulation3, and development in multicellular organisms4. Single-cell sequencing encompasses hundreds of techniques with different approaches to studying the genomes, transcriptomes, epigenomes, and other omics of individual cells. The analysis of single-cell sequencing data i...

      Introduction to Single-Cell Sequencing
      by seqadmin
      Single-cell sequencing is a technique used to investigate the genome, transcriptome, epigenome, and other omics of individual cells using high-throughput sequencing. This technology has provided many scientific breakthroughs and continues to be applied across many fields, including microbiology, oncology, immunology, neurobiology, precision medicine, and stem cell research.

      The advancement of single-cell sequencing began in 2009 when Tang et al. investigated the single-cell transcriptomes
