We conducted a series of literature searches to prioritise autosomal genes for analysis, focusing on genes that had an association with childhood speech and language disorders and that were relevant for synaptic function see Appendix 4. Rattlesnake microchromosomes deviate significantly from this macrochromosomal pattern and share disproportionately high frequencies of contacts with other chromosomes, including other microchromosomes Fig.
Participants Sex chromosome trisomies: After excluding children with missing or inadequate DNA, participants included 42 girls with trisomy X, 43 boys with Klinefelter syndrome, and 45 boys with XYY.

This stage 1 registered report describes a planned genetic association study relating common SNPs within two candidate genes to language and global neurodevelopment phenotypes in sex chromosome trisomy SCT. The description of variants selected could be slightly improved, however, especially with respect to handling LD patterns.
Genomic context for venom gene regulation and production. In addition, handedness and language laterality were assessed. Its resolution ranges from single copy to entire genome sequences.
How to cite this report:. Identification and analysis of sex chromosomes by comparative genomic hybridization CGH. Asterisks depict significant differences between autosomal and Z Chromosome expression. We identify the rattlesnake Z Chromosome, including the recombining pseudoautosomal region, and find evidence for partial dosage compensation driven by an evolutionary accumulation of a female-biased up-regulation mechanism.
