Homozygosity and risk of childhood death due to invasive bacterial disease. [PDF]

, 2009
BACKGROUND: Genetic heterozygosity is increasingly being shown to be a key predictor of fitness in natural populations, both through inbreeding depression, inbred individuals having low heterozygosity, and also through chance linkage between a marker and

Voter models with heterozygosity selection

, 2008
This paper studies variations of the usual voter model that favor types that are locally less common. Such models are dual to certain systems of branching annihilating random walks that are parity preserving.

LRRC8A Regulates Outer Hair Cell Volume and Electromotility and is Required for Hearing

Advanced Science, EarlyView.
This study identifies LRRC8A‐dependent volume‐regulated anion channels (VRACs) as essential for cochlear outer hair cells' electromotility and auditory signal amplification. LRRC8A deficiency disrupts cell volume control, impairs auditory sensitivity, and causes deafness, while targeted LRRC8A re‐expression restores auditory function.

Single-Gene Deletions Contributing to Loss of Heterozygosity in Saccharomyces cerevisiae: Genome-Wide Screens and Reproducibility

G3: Genes, Genomes, Genetics, 2019
Loss of heterozygosity (LOH) is a phenomenon commonly observed in cancers; the loss of chromosomal regions can be both causal and indicative of underlying genome instability.

Epigenetic loss of heterozygosity of Apc and an inflammation-associated mutational signature detected in Lrig1 +/− -driven murine colonic adenomas

BMC Cancer, 2020
Background The loss of a single copy of adenomatous polyposis coli (Apc) in leucine-rich repeats and immunoglobulin-like domains 1 (Lrig1)-expressing colonic progenitor cells induces rapid growth of adenomas in mice with high penetrance and multiplicity.

Levels of genetic polymorphism: marker loci versus quantitative traits [PDF]

, 1998
Species are the units used to measure ecological diversity and alleles are the units of genetic diversity. Genetic variation within and among species has been documented most extensively using allozyme electrophoresis.

Exome Sequencing Reveals the Genetic Architecture of Non‐syndromic Orofacial Clefts and Identifies BOC as a Novel Causal Gene

Advanced Science, EarlyView.
Nonsyndromic orofacial clefts (NSOFCs) are the most common craniofacial defects. Exome sequencing of 214 sporadic cases sheds new light on its genetic architecture and identifies many candidate pathogenic variants. Furthermore, functional studies establish BOC as a novel causal gene and reveal an unusual two‐locus model of inheritance via the epistatic

IncRNA‐ZFAS1, an Emerging Gate‐Keeper in DNA Damage‐Dependent Transcriptional Regulation

Advanced Science, EarlyView.
LncZFAS1 plays a crucial role during DNA damage response in mammalian cells. Loss of lncZFAS1 results in deficient DNA lesion removal and reduced cell viability. Mechanistically, lncZFAS1 modulates RNAPII phosphorylation and transcription and thereby promotes both GG‐NER and TC‐NER upon UV damage.

TP53 Abnormalities are frequent and early events in the sequential pathogenesis of gallbladder carcinoma§

Annals of Hepatology, 2005
Background: Gallbladder carcinoma (GBC) is a frequent neoplasm in Hispanic and native American populations. GBC is preceded by gallstones, chronic cholecystitis and dysplastic changes of the gallbladder epithelium.
