Archaic Introgression Shaped Human Circadian Traits | Genome Biology and Evolution

Abstract When the ancestors of modern Eurasians migrated out of Africa and interbred with Eurasian archaic hominins, namely, Neanderthals and Denisovans, DNA of archaic ancestry integrated into the genomes of anatomically modern humans. This process potentially accelerated adaptation to Eurasian environmental factors, including reduced ultraviolet radiation and increased variation in…

Blastn DB issue

Hello ! I’m currently trying to develop a local core-genome MLST tool using a combination of a huge genes database and blastn but I came into outputs I can’t explain. Here’s what I have: My genome: genome.fasta My database, comprised of ~1000 genes and n alleles: db/GENE01.fasta: 1500 sequences. db/GENE02.fasta:…

Effect allele flipping

Dear Sam and all, I used PRSice for calculating PRS based on the well-known 30 SNP list that is specific for type 1 diabets. I found that PRSice version 2.6.1 considered only SNPs whose effect allele are alternative alleles in the target file for PRS calculation. All SNPs that thier…

Genome haplarithmisis sheds light on complex genetic landscape of miscarriages

About 10-15% of pregnancies fail after conception has been recognized, amounting to 23 million losses a year. Chromosomal anomalies underlie many embryonic and fetal losses, but their exact frequency and localization to the embryo or placenta are still unclear. A new study published in Nature Medicine reports on a chromosomal…

Genetic data QC prior to imputation

Hi there, Should SNPs that have this sort of name ‘exm_….” be removed from genetic data at the QC stage. Not necessarily, they used this ID cause it was part of their ExomeSNP array, probably because there was no RSID at the time, for example this one: www.ncbi.nlm.nih.gov/projects/SNP/snp_ss.cgi?subsnp_id=ss1958317049 Should SNPs…

Integrative lncRNA, circRNA, and mRNA analysis reveals expression profiles of six forensic body fluids/tissue

RNAs have attracted much attention in forensic body fluid/tissue identification (BFID) due to their tissue-specific expression characteristics. Among RNAs, long RNAs (e.g., mRNA) have a higher probability of containing more polymorphic sites that can be used to assign the specific donor of the body fluid/tissue. However, few studies have characterized…
