Fig. 3.

Gene map and polymorphisms identified in the chicken interferon-induced transmembrane protein 3 (IFITM3) gene on chromosome 5. The open reading frame (ORF) within the exons is indicated by shaded blocks, and the 5′ and 3′ untranslated regions (UTRs) are indicated by white blocks. Edged horizontal bars indicate the regions sequenced. Arrows indicate the polymorphisms found in this study. Asterisks denote non-synonymous single nucleotide polymorphisms (SNPs). The Y-shaped bar indicates the insertion/deletion identified in the IFITM3 gene
