Disease relevance of DNAI2


High impact information on DNAI2

  • Significantly, gene expression associated with ciliogenesis is evident in bronchial epithelium, and includes the expression of transcripts specifying axonemal proteins DNAI2, SPAG6, ASP, and FOXJ1 transcription factor [2].
  • However, ten intragenic polymorphic sites and an EcoRI RFLP have been identified, allowing the exclusion of DNAI2 in three consanguineous families [1].
  • DNAI2, which is composed of 14 exons located at 17q25, is highly expressed in trachea and testis [1].
