(genetics)
A gene whose phenotypic expression is easily discerned and thereby can be used to identify an individual or a cell that carries it, or as a probe to mark a nucleus, chromosome, or locus.

In this study, genetic determinants for antibiotic resistance were identified using molecular methods like PCR and this provided important evidences for horizontal transmission.
The major genetic determinants are the DR3 and DR4 alleles (or variants) of a group of genes called the HLA complex.
A better understanding of the environmental and genetic determinants of plasma BCAA signaling would help to advance this exciting field, as investigators continue to unravel the complex relations between diet-influenced metabolites, disease-related metabolic signaling, and cardiometabolic risk.
The conference included a plenary lecture that sought to provide a high-level picture of the fields of epigenetics, epigenomics, genetics, and genomics; routine and state-of-the-art technologies and approaches to study genetic determinants and epigenetic changes caused by different stimuli; and future trends describing the role that these fields and approaches will play in studying the molecular pathology of infectious diseases.
They address pain terminology, epidemiology, and basic science mechanisms, as well as differences associated with sex, gender, age, and genetic determinants of variability; management through education, exercise, electrical stimulation, physical agents, and manual therapy; an interdisciplinary approach involving medical and psychological management; and common syndromes, such as myofascial pain, fibromyalgia, spinal pain, migraine, temporomandibular disorder, osteoarthritis and rheumatoid arthritis, neuropathic pain, and complex regional pain syndrome, with discussion of an evidence-based approach to medical, psychological, and physical therapy management for each.
Finding that several of the disorders that manifest early in life have some genetic determinants of the neurodevelopmental process in common does not prove that they should be included in a single diagnostic group.
Researchers are focusing on novel risk factors, including malignant forms of cholesterol (previous research has suggested that South Asians may have smaller and denser cholesterol particles that are more prone to causing hardening of the arteries), as well as other social, cultural and genetic determinants.
Pharmacogenomics is a discipline that studies the genetic determinants of individual variation in response to a given drug, aiming to facilitate the personalization of therapy through genotype-informed selection of a drug and/or dose in order to predict and improve the responsiveness to therapy, as well as to minimize the risk of adverse drug reactions (ADRs) [2].
It is likely that for a given polygenic condition there might be other population-specific genetic determinants. Thus, further work will be required to confirm these observations and to study the mechanism by which the coding variants so far identified affect bone cell function and modulate bone mass.
