21. Thus, while the biosynthetic gene cluster suggests SLS is a LAP, structural confirmation is lacking. 22. This gene is mapped to chromosome 11p15, where it resides within a TRIM gene cluster . 23. Loss of genes is dependent of the number of genes originating in the gene cluster . 24. This gene is mapped to chromosome 19, where it resides within an apolipoprotein gene cluster . 25. Furthermore, this biosynthetic gene region is interrupted by a cryptic type II PKS gene cluster . 26. All the ParaHox genes in the amphioxus genome are therefore in the ParaHox gene cluster . 27. This gene and three other genes form a cytokine receptor gene cluster on chromosome 2q12. 28. There are total 21 genes ( tsrA ~ tsrU ) in the biosynthetic gene cluster . 29. This gene encodes a deubiquitinating enzyme which lies in a gene cluster on chromosome Xp11.23 30. This gene is mapped to the region where the chemokine receptor gene cluster is located.
