41. The chromosomal locus containing the SNORD115 gene cluster has been duplicated in many individuals with autistic traits. 42. Large portions of the gene cluster " psyD " have very close counterparts in the pederin gene clusters. 43. In the house mouse, the major MUP gene cluster provides a highly polymorphic scent signal of genetic identity. 44. LPS gene clusters are highly variable between different strains, subspecies, species of bacterial pathogens of plants and animals. 45. Most of the time, homeodomain proteins act in the Hox gene clusters and by other genes throughout the genome. 46. Three genes encoding alpha, beta and gamma subunits are tandemly organized in a genomic segment as a gene cluster . 47. The more recent model describes a STX gene cluster ( sxt ) used to obtain a more favorable reaction. 48. This gene and seven other chemokine receptor genes form a chemokine receptor gene cluster on the chromosomal region 3p21. 49. This gene and five other closely related cytokine genes form a gene cluster spanning approximately 400 kb on chromosome 2. 50. U25 is found in gene clusters in plants and within the U22 snoRNA host gene ( UHG ) in mammals.
