  • Seaching for mutation of a single gene from numerous genomes

    Hi all,

    I am pretty new in bioinformatics and I need help for one of my project. I am currently studying quite a few of genes from 50+ genomes. The objective is to investigate the mutation presence in these genes. I want to know which nucleotide (e.g. G152A, C1854G) and which codon (V57I, L162F) has the mutation.

    What I currently do is alignt the gene using MEGA and search for mutation sequence by sequence.

    May I know what are the faster ways to do this kind of mutation search?

    Thank you so much

    If you have cDNA go to 152*3 for G152A mutation
    in normal codon usage G to A mutation happens by codons GAX->GGX similarly if you keep codon table in front of you and look into mutations, it is easy to guess what is mutated and the trace on cDNA or genomic region.

      I am doing that, but investigating 18 genes from 62 bactertial genomes using MEGA can be pretty slow. Wonder is that any software which I can use to speed up the process. :-)

        Exploring the Dynamics of the Tumor Microenvironment
        by seqadmin




        The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

        Exploring Human Diversity Through Large-Scale Omics
        by seqadmin


        In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
