The allele frequency net database (AFND, http://www.allelefrequencies.net ) is an online web-based repository that contains information on the frequencies of immune-related genes and their corresponding alleles in worldwide human populations. At present, the website contains data from 1784 population samples in more than 14 million individuals from 129 countries on the frequency of genes from different polymorphic regions including data for the human leukocyte antigen (HLA) system. In addition, over the last four years, AFND has also incorporated genotype raw data from 85,000 individuals comprising 215 population samples from 39 countries. Moreover, more population data sets containing next generation sequencing data spanning >3 million individuals have been added. This resource has been widely used in a variety of contexts such as histocompatibility, immunology, epidemiology, pharmacogenetics, epitope prediction algorithms for population coverage in vaccine development, population genetics, among many others. In this chapter, we present an update of the most used searching mechanisms as described in a previous volume and some of the latest developments included in AFND.

In many model organisms, the circadian system has been proposed to comprise multiple oscillators that interact to promote accuracy of the clock as well as intricacies of rhythmic outputs. In Neurospora crassa, the circadian transcriptional/translational loop comprising of the FRQ (Frequency) and WCC (White Collar Complex) proteins has been instrumental in explaining many attributes of the clock including entrainment and rhythms in development and gene expression; in addition, some non-circadian oscillations can be unmasked when the FRQ-WCC feedback loop is eliminated. These rhythms have often lost defining circadian characteristics and are potentially controlled by other oscillators, termed FRQ-less oscillators (FLOs) in Neurospora.

Background: The second most common cause of autosomal recessive early-onset Parkinson's disease (PD) can be attributed to mutations in the PINK1 gene, malfunction of the mitochondria is the key pathological mechanism. Bre1 encodes an E3 ubiquitin ligase, with the discovery of Bre1's role in repairing mitochondrial damage, further investigation into its implications for PD is warranted.
Methods: We used the PINK1B9 drosophila melanogaster as the PD model.

The AUA isoleucine codon is generally rare and used with varying frequency in bacterial genomes. The tRNA responsible for decoding this trinucleotide must be modified at the wobble position by tRNA lysidine synthetase (TilS) prior to aminoacylation and accommodation at the ribosome. To test the hypothesis that TilS catalytic efficiency correlates with AUA frequency, we cloned tilS genes from bacteria with varying AUA codon usage.

The aim of this study was to investigate three unrelated Simmental calves with atypical white coat color, identify potential genetic causes using a trio-based whole-genome sequencing approach, and assess the prevalence of the identified variants in the breed. Several inherited alleles affecting coat color, ranging from fawn to red spotted and white-headed, have been described in Simmental cattle originating from Switzerland. However, no genetic variant has yet been associated with an almost completely white coat in this breed.

Background: Cisplatin is a commonly used chemotherapeutic across numerous cancer types that can cause neurotoxicities in patients, including peripheral sensory neuropathy, tinnitus, hearing loss, and vertigo.
Objective: We aimed to evaluate, for the first time, how genetic ancestry impacts cisplatin-induced neurotoxicities and if disparities are related to population differences in allele frequency.
Methods: In a cohort of cisplatin-treated testicular cancer survivors, relationships between genetic ancestry and neurotoxicities, medications, and lifestyle factors were assessed using logistic regression and Kruskal-Wallis tests and multiple pairwise comparisons using the Wilcoxon rank-sum test (Benjamini-Hochberg adjustment).
