nstd89 (de Boer et al. 2014)
- Organism:
- Human
- Study Type:
- Case-Set
- Submitter:
- Martin de Boer
- Description:
- We report a novel LINE1-mediated insertion of a transcript from the TMF1 gene on chromosome 3 into the CYBB gene on the X chromosome in a Dutch male patient with chronic granulomatous disease. A 5.8-kb, incomplete and partly exonized TMF1 transcript was identified in intron 1 of CYBB in opposite orientation to the host gene. The sequence of the insertion showed the hallmarks of a retrotransposition event, with an antisense poly A tail, target site duplication and a consensus LINE1 endonuclease cleavage site. This insertion induced aberrant CYBB mRNA splicing, with inclusion of an extra 117-bp exon between exons 1 and 2 of CYBB. This extra exon contained a premature stop codon.
