  • The results showed that the E3 allele had the highest frequency (0.744), followed by E4 (0.198) and E2 (0.058). (wayne.edu)
  • Each scenario's results were averaged over ten replicates and changes in horned allele frequency, levels of inbreeding and genetic gain were determined. (usda.gov)
  • Most pathology related to AT-D is linked to the Z allele and, in clinical practice, 96% of patients have a ZZ phenotype 3 - 6 . (ersjournals.com)
  • To address this, Dr. Morikawa and colleagues evaluated the feasibility of performing gene panel tests using cytological specimens including transbronchial brushing, transbronchial needle aspiration, and pleural effusion in clinical practice. (eurekalert.org)
  • Objective -To determine whether hyperuricosuria was a predisposing factor for urate urolithiasis in Bulldogs and Black Russian Terriers (BRTs) and to estimate the allele frequency of the Cys181Phe genetic mutation in urate transporter SLC2A9 in these breeds. (avma.org)
  • Now instead of letters P and Q you plug in allele frequency based on the statistical method where 1.00 is unity or 100%---so 10% is .10 and 90% is .9---you get the picture. (stormfront.org)
  • The correlation coefficient of the gene allele ratio in 61 cases compared with the tissue sample was 0.717, showing a high correlation. (eurekalert.org)
  • ² Distribution - Graphical distribution of the allele. (allelefrequencies.net)
  • Allele frequencies and their distribution in genes and pathways were analyzed with single variant and SKAT-O tests. (figshare.com)
  • CEST) -- Personalized medicine for lung cancer using molecular-targeted drugs is common but there have been no prospective validation studies done on the usefulness of lung cancer gene panel testing using cytology samples. (eurekalert.org)
  • The most common OCA2 variant is a large deletion in the gene, which is found in many affected individuals of sub-Saharan African heritage. (medlineplus.gov)
  • 61 Mendelian Diseases, 151 Primary Immunodeficiency Diseases(PID) and 5 DPWG recommeded Essential pharmacogenetic(PGx) genes were analyzed. (researchsquare.com)
  • Gene-environment interactions are an example of phenotypic plasticity . (berkeley.edu)
  • Several functional studies have reported that the Ahl gene renders mice more susceptible to noise -induced hearing loss (NIHL) than strains which do not carry this gene [e.g. (cdc.gov)
  • Functional data from each mouse were aligned with the cytocochleogram using the frequency-place map of Ou et al. (cdc.gov)
  • The success rate of gene analysis using cytological specimens was extremely high, and the yield and quality of the extracted nucleic acid were also sufficient for panel analysis," Dr. Morikawa reported. (eurekalert.org)
  • The allele frequency of the mutation was high in both breeds, and DNA testing can be used to select against the mutation. (avma.org)
  • The observation of an allele with a high frequency in the Tibetans and low frequency in the Han might have been caused by selection favoring the allele in the Tibetans (and so might be related to adaptation to high altitudes) or by selection acting against the allele the Han (and so have nothing at all to do with adaptation to high altitudes). (berkeley.edu)
  • Furthermore, the Han and Danish had similar allele frequencies for this gene, while the Tibetans alone had a high frequency of two unusual alleles - which suggests that selection favored those particular alleles in the Tibetans. (berkeley.edu)
  • Identification of high-penetrance breast cancer genes such as Brca1 has been accomplished by analysing familial cases. (mcw.edu)
  • It has been shown that these mice begin losing high-frequency hearing at two months. (cdc.gov)
