Population genomic analysis of elongated skulls reveals extensive female biased immigration in Early Medieval Bavaria

2018
Proc Natl Acad Sci U S A
PMCID: 5879695
PMID: 29531040
DOI: 10.1073/pnas.1719880115

[…] (SI Appendix, section 7), many of which are thought to have changed frequencies in human populations over the last 10,000 y due to adaptation to different environments and changing diet. Based on the HIrisPlex system (), the majority (∼80%) of individuals with normal or intermediate skulls (and thus northern/central European ancestry) showed high probabilities for blue eyes and blonde hair (SI App […]

Predicting hair cortisol levels with hair pigmentation genes: a possible hair pigmentation bias

2017
Sci Rep
PMCID: 5561185
PMID: 28819144
DOI: 10.1038/s41598-017-07034-w

[…] Hardy-Weinberg equilibrium (p < 10−7). Excess heterozygosity, gender accuracy, and relatedness were tested. We used MACH 1.0 to impute to the 1000 Genomes Iv3 reference .We selected 22 SNPs from the HIrisPlex System related to hair color prediction. Nine SNPs were directly genotyped in Generation R and 13 were available as imputed genotypes. Of these, 3 were excluded due to poor imputation qualit […]

[…] ior distribution of the genotypes g given the read counts r of the reference allele and t of the total reads covering a site. We took 100 random genotype samples per individuals and submitted them to HIrisPlex, obtaining an estimate of the uncertainty of phenotype inference (, section 4; ). […]

Paleogenomic Evidence for Multi generational Mixing between Neolithic Farmers and Mesolithic Hunter Gatherers in the Lower Danube Basin

2017
Curr Biol
PMCID: 5483232
PMID: 28552360
DOI: 10.1016/j.cub.2017.05.023

[…] 0 and positions covered by at least 3 reads. Owing to the low coverage of some of the genomes, the identification of the genotype as homozygous or heterozygous was inconclusive at some positions. The Hirisplex [] and 8-plex [] prediction systems were used to predict eye, hair and skin color in the ancient samples. Furthermore, we also investigated loci related to lactase persistence.We used imputa […]

Global skin colour prediction from DNA

2017

[…] al. , ; Valenzuela et al. ; Valverde et al. ; Voisey et al. ), 22 of which proved decidedly predictive for hair colour categories (Branicki et al. ). From this, and previous eye colour knowledge, the HIrisPlex system was developed and forensically validated for combined eye and hair colour prediction from DNA achieving AUCs of 0.92 for red, 0.85 for black, 0.81 for blond, and 0.75 for brown (Draus […]

[…] ingle multiplex assay targeting 12-eye colour SNPs. We used 6 SNPs that were previously identified to predict categorical eye colour in genome wide studies) and which are included in the IrisPlex and HIrisPlex DNA test systems for categorical eye colour prediction: HERC2 rs12913832, OCA2 rs1800407, SLC24A4 rs12896399, SLC45A2 (MATP) rs16891982, TYR rs1393350, and IRF4 rs12203592. The 6 additional […]
