Reviewing thousands of genome wide associate studies (GWAS) to identify genetic variants in single nucleotide polymorphisms (SNPs), investigators at Dartmouth's Norris Cotton Cancer Center found that some alleles (one of a pair of genes located on a specific chromosome) are more frequently risk - associated with disease than protective.

The team found that a mutation in a single pair of nucleotides in the gene causes seed coat permeability — that is, a change in one pair out of the approximately 1 billion base pairs that make up the soybean genome.

In a population with so few individuals, an unhealthy mutant gene will more often find itself paired with the same mutant gene in an offspring because the parents are related and of similar genetic makeup.

In doing so, they found that many genes thought to be nonessential to life were actually one - half of gene pairs with the same function.

By utilizing paired genome - wide high - throughput DNA sequencing (DNA - seq) with RNA - seq, we found that gene dosage, at the level of individual genes or chromosomal «somy» (a general term covering disomy, trisomy, tetrasomy, etc.), accounted for greater than 85 % of total gene expression variation in genes with a 2-fold or greater change in expression.
