    There's no hard and fast rule that I'm aware of. In general, the greater the consanguinity the more likely the variant is homozygous.

    @ dpryan - There is a few incidents of consanguinity in the family but since I am looking at a complex disease (asthma), compound heterozygosity is also a possibility. Can you please tell me how can we decide which model fits best?

    @blancha - Thank you for the suggestion. I would try it.. Thanks again

    Are you positive that they're homozygous and not compound heterozygous? The latter would be more likely unless they're consanguineous.

    For your second question, how about ClinVar?
    ClinVar archives and aggregates information about relationships among variation and human health.

  • Exome sequencing for homozygous recessive disease

    I am naive in the field of genomics. Please guide me through these questions.

    If I have exome sequencing data of a family with a homozygous recessive disease, how should I analyze the data?Do we assume that the cases should be homozygous for a given genotype and controls as heterozygous?

    Also, are there any tool/webpage that help us identify known SNPs associated to a particular disease? I want to check if the SNPs that I have obtained are previously known to be associated with my disease of interest?

    Recent Advances in Sequencing Analysis Tools
    by seqadmin


    The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin




    The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...
