Mouse Gatd3a Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Gatd3a Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Gatd3a conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Gatd3a gene (NCBI Reference Sequence: NM_138601.2 ; Ensembl: ENSMUSG00000053329 ) is located on Mouse chromosome 10. 7 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 7 (Transcript: ENSMUST00000001242). Exon 5~6 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Gatd3a gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-77O11 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 5 starts from about 53.01% of the coding region. The knockout of Exon 5~6 will result in frameshift of the gene. The size of intron 4 for 5'-loxP site insertion: 2464 bp, and the size of intron 6 for 3'-loxP site insertion: 678 bp. The size of effective cKO region: ~2034 bp. The cKO region does not have any other known gene.

Tandem repeats are found in the dot plot matrix. It may be difficult to construct this targeting vector. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(8534bp) | A(20.81% 1776) | C(27.53% 2349) | T(24.99% 2133) | G(26.67% 2276) Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

  • Novel Gene Discovery in Primary Ciliary Dyskinesia
    Novel Gene Discovery in Primary Ciliary Dyskinesia Mahmoud Raafat Fassad Genetics and Genomic Medicine Programme Great Ormond Street Institute of Child Health University College London A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy University College London 1 Declaration I, Mahmoud Raafat Fassad, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 2 Abstract Primary Ciliary Dyskinesia (PCD) is one of the ‘ciliopathies’, genetic disorders affecting either cilia structure or function. PCD is a rare recessive disease caused by defective motile cilia. Affected individuals manifest with neonatal respiratory distress, chronic wet cough, upper respiratory tract problems, progressive lung disease resulting in bronchiectasis, laterality problems including heart defects and adult infertility. Early diagnosis and management are essential for better respiratory disease prognosis. PCD is a highly genetically heterogeneous disorder with causal mutations identified in 36 genes that account for the disease in about 70% of PCD cases, suggesting that additional genes remain to be discovered. Targeted next generation sequencing was used for genetic screening of a cohort of patients with confirmed or suggestive PCD diagnosis. The use of multi-gene panel sequencing yielded a high diagnostic output (> 70%) with mutations identified in known PCD genes. Over half of these mutations were novel alleles, expanding the mutation spectrum in PCD genes. The inclusion of patients from various ethnic backgrounds revealed a striking impact of ethnicity on the composition of disease alleles uncovering a significant genetic stratification of PCD in different populations.

  • Human Transcription Factor and Protein Kinase Gene Fusions in Human Cancer Kari Salokas, Rigbe G
    www.nature.com/scientificreports OPEN Human transcription factor and protein kinase gene fusions in human cancer Kari Salokas, Rigbe G. Weldatsadik & Markku Varjosalo* Oncogenic gene fusions are estimated to account for up-to 20% of cancer morbidity. Recently sequence-level studies have established oncofusions throughout all tissue types. However, the functional implications of the identifed oncofusions have often not been investigated. In this study, identifed oncofusions from a fusion detection approach (DEEPEST) were analyzed in detail. Of the 28,863 oncofusions, we found almost 30% are expected to produce functional proteins with features from both parent genes. Kinases and transcription factors were the main gene families of the protein producing fusions. Considering their role as initiators, actors, and termination points of cellular signaling pathways, we focused our in-depth analyses on them. Domain architecture of the fusions and their wild-type interactors suggests that abnormal molecular context of protein domains caused by fusion events may unlock the oncogenic potential of the wild type counterparts of the fusion proteins. To understand overall oncofusion efects, we performed diferential expression analysis using TCGA cancer project samples. Results indicated oncofusion-specifc alterations in gene expression levels, and lower expression levels of components of key cellular pathways, in particular signal transduction and transcription regulation. The sum of results suggests that kinase and transcription factor oncofusions deregulate cellular signaling, possibly via acquiring novel functions. At any given moment, multitudes of molecular networks are activated in cells throughout the body. An impor- tant feature of these networks is highly concerted regulation of key signaling, and deviation from homeostasis can result in diseases, such as cancer.

  • Mouse Pwp2 Conditional Knockout Project (CRISPR/Cas9)
    https://www.alphaknockout.com Mouse Pwp2 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Pwp2 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Pwp2 gene (NCBI Reference Sequence: NM_029546 ; Ensembl: ENSMUSG00000032834 ) is located on Mouse chromosome 10. 21 exons are identified, with the ATG start codon in exon 1 and the TAG stop codon in exon 21 (Transcript: ENSMUST00000042556). Exon 2 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Pwp2 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-77O11 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 2 starts from about 0.69% of the coding region. The knockout of Exon 2 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 900 bp, and the size of intron 2 for 3'-loxP site insertion: 1017 bp. The size of effective cKO region: ~613 bp. The cKO region does not have any other known gene.

  • Genome-Wide Detection of CNV Regions and Their
    Qiu et al. BMC Genomics (2021) 22:332 https://doi.org/10.1186/s12864-021-07654-7 RESEARCH ARTICLE Open Access Genome-wide detection of CNV regions and their potential association with growth and fatness traits in Duroc pigs Yibin Qiu1†, Rongrong Ding1,2†, Zhanwei Zhuang1, Jie Wu1, Ming Yang2, Shenping Zhou1, Yong Ye1, Qian Geng1, Zheng Xu1,3, Sixiu Huang1, Gengyuan Cai1,2,3, Zhenfang Wu1,2,3* and Jie Yang1,3* Abstract Background: In the process of pig breeding, the average daily gain (ADG), days to 100 kg (AGE), and backfat thickness (BFT) are directly related to growth rate and fatness. However, the genetic mechanisms involved are not well understood. Copy number variation (CNV), an important source of genetic diversity, can affect a variety of complex traits and diseases and has gradually been thrust into the limelight. In this study, we reported the genome-wide CNVs of Duroc pigs using SNP genotyping data from 6627 animals. We also performed a copy number variation region (CNVR)-based genome-wide association studies (GWAS) for growth and fatness traits in two Duroc populations. Results: Our study identified 953 nonredundant CNVRs in U.S. and Canadian Duroc pigs, covering 246.89 Mb (~ 10.90%) of the pig autosomal genome. Of these, 802 CNVRs were in U.S. Duroc pigs with 499 CNVRs were in Canadian Duroc pigs, indicating 348 CNVRs were shared by the two populations. Experimentally, 77.8% of nine randomly selected CNVRs were validated through quantitative PCR (qPCR). We also identified 35 CNVRs with significant association with growth and fatness traits using CNVR-based GWAS.
