Copy number variations (CNVs) are a pervasive form of genomic variation that entail duplications or deletions of DNA segments ranging from kilobases to megabases. In animal genomes, CNVs contribute ...

Genetic variants that cause rare disorders may remain elusive even after expansive testing, such as exome sequencing. The diagnostic yield of genome sequencing, particularly after a negative ...

A study led by UCLA Health Jonsson Comprehensive Cancer Center investigators reveals how melanoma, the deadliest form of skin cancer, evolves to resist immunotherapy and identifies a potential ...

Large and rare duplications and deletions in a chromosome region known as 22q11.2 , which involves genes that regulate cardiac development, are linked to nonsyndromic bicuspid aortic valve disease.

Copy number variation (CNV) refers to an increase or decrease in the number of copies of a DNA sequence in a genome, which can subsequently be implicit in promoting aberrant gene expression patterns ...

Genetic ancestry plays a key role in determining the behavior of head and neck tumors and may help explain why African-American patients survive for half as long as their counterparts of European ...

Accurate prediction of CYP2D6 activity from genotype data is of utmost importance as CYP2D6 pharmacogenetic (PGx) testing is increasingly used to guide drug therapy. However, given the complexity of ...

Standard laboratory tests can fail to detect many disease-causing DNA changes. Now, a novel 3D chromosome mapping method can reliably reveal these hidden structural variants and lead to new ...
