Comparison of maternal trisomy and disomy (CB131,126,117,125,122,121) with Paternal trisomy and disomy (CB091,089,087,093,100,103)

-the limited variation in paternal disomy and trisomy is conserved

-maternal still has variation

-there is no clear divide between gender along PC1--what does this mean?

Sorting of paternal trisomy data(Emilie) and maternal trisomy data (Jon):

Use galaxy sort tool to sort p-value in ascending order

Why is it that for many of the data there is a base mean and all statistics but no p-value?

Filtered data on galaxy to remove data with 'NA' -skip 0 header line- Only retained 70.41% of data when filtering to remove 'NA'

Copied data to excel and use shortcut to removal decimals without rounding

CENPA Gene (Centromere Protein A) located on Chromosome 5, 16.76

"Phenotype Overview: cardiovascular system, cellular, craniofacial, embryo, growth/size/body, mortality/aging, nervous system"

"A mutation in this gene can cause chromosomal missegregation, aneuploidy and apoptosis"

CENPA segmental haploidy of chr5 in mice is known to cause Wolf-Hirschhorn syndrome -conserved synteny to human 4p16.3

Symptoms:

-'Greek warrior helmut facial appearance'

-mental retardation

-Black Lab discoveries give insight into genetic inheritance -CENP-A could be the 'key' epigenetic marker protein -CENP-A changes shape of the nucleosome

Going forward:Want to investigate the CENP-A gene in maternal strains
