CCR4 and telangiectasis: The majority of these genes belonged to the category of “reduced virulence” in the PHI-base, while others belonged to different categories, including “loss of pathogenicity” (chitin synthase, GTP-binding protein, ATP-binding cassette (ABC) transporter, alpha-mannosyltransferase cmt1 and cytochrome p450) and “lethal” (ataxia telangiectasia mutated, C6 transcription factor, protein transport protein, ccr4-not transcription complex subunit) (Supplementary Table S6).
