Genetic and environmental factors are the main key factor in the mechanism of various diseases. Previous studies have shown that environmental factors can also be the main cause in the pathogenesis of most diseases. The review details a brief overview discussing the environmental and genetic factors influencing the diseases. This review also emphasizes the findings categorizing the common diseases on the basis of genetic profiles, disease diagnosis, and treatment based on the genetic influence.
Genetic, diseases, Pathogenesis, risk factor
Genetic syndrome is basically genetic problem which is caused due to abnormality in individual’s total genetic content. Abnormality can be minor i:e single base mutation or major i:e involve in the entire chromosome. Some diseases like cancer occur due to abnormality in genes or chromosomes or can be caused/influenced by environmental factors. If a syndrome is caused by the combination of both genetic and environmental factor and then genetical origin of the diseases can be referred as having multifactorial system. Various diseases including cancers along with a plethora of other diseases, are concluded to be a result of environmental triggers.
• Sickle cell disease
• Attention deficit hyperactivity disorder
• Chronic Neutrophilic leukemia
• Oral-facial-digital syndrome
• Arterial Thrombosis
• Insulin dependent diabetes mellitus
• Huntington’s disease
• Breast Cancer
Sickle cell disease is also known as sickle cell anaemia comes under hereditary blood disorder, that affects haemoglobin. The pathology of sickle cell sickness, caused by sickling appearance. In this disorder the body makes sickle shaped red blood cells. In deoxy state hemoglobin S molecules aggregate into long polymers that are aligned for the formation of liquid crystals known as “tactoids”. In the presence of tactoids the red cell is transformed into the characteristic sickle shaped cell is the reason for the particle disease name. There is increase in blood viscosity formed with small vessel stasis and obstruction, which leads to organ damage. Furthermore patients having sickle cell disease have a propensity to bacterial infection owing to combination of many disorder . Apart from that the effect of environmental factors, the occurance of non-communicable diseases are determined by non-genetic and genetic developmental factors . Attention deficit hyperactivity disorder (ADHD) is one of the most common disorder. It is commonly studied and diagnosed psychiatric disorder in children, affecting about 3 to 5% of children worldwide . Chronic neutrophilic leukemia (CNL) is a rare myeloproliferative disorder characterized by persistent mature neutrophilia in peripheral blood. Because the disease entity is rare, and because it is typically a diagnosis of exclusion, it is important for pathologist to be familiar with CNL when approaching the patient with a myeloproliferative clinical picture . Preoperative Iron deficiency anaemia (IDA) is common with poor postoperative outcomes. Standard treatment includes oral iron supplementation and allogenic blood transfusion. This trial demonstrates that intravenous iron is both a feasible and effective treatment for IDA in anemic colorectal cancer patients [5-15]. Arterial thrombosis is a blood clot inside blood vessel. It blocks the flow of blood in the circulatory system. Huntington’s disease is a neurodegenerative disorder which affects muscle coordination leads to mental symptoms. It first affects the brain, with gradual loss of control of memory and mental capability. Breast cancer is a type of cancer that develops from cell of breast or may be a lump in breast. One study shows the possibility of using ANXA7 as both a clinically relevant indicator of disease progression and a prognostic biomarker for survival in the patients with triple negative breast cancer. ANXA7 might serve as promising target for triple negative breast cancer therapy. The gene for Huntington disease on the fourth chromosome has been characterized [16-38]. Gastrointestinal diseases are functional disorders, as being dominant in women, but others, as being more common in men. The pathogeneses of gastrointestinal diseases are still unclear but steroid sex hormones play important role in the pathogenesis of several gastrointestinal diseases [39-43]. Type 1diabetes mainly known as insulin dependent diabetes mellitus (IDDM) is documented as an autoimmune disease in which pancreatic islet cells are progressively destroyed. The highest degree of enzyme specificity and fluorescence sensitivity arrows that enzyme inhibition assay is simpler, accurate and sensitive for screening a large number of serum samples) [44-47]. Schizophrenia is a psychiatric disorder characterized by abnormalities including elusions, conceptual disorganization, cognitive impairment, and hallucinations. However, investigations are required to illuminate the enlarge frequency of the D allele among schizophrenia patients . Irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) damages the tissue of the small bowl and large bowel through the process of inflammation. Gastrointestinal diseases are recognized, as being dominant in women, but others are more common in men (Anal fistulae). The observations elevate concerns about the involvement of sex steroid hormones in the pathogeneses of these diseases . This prospective study assessed potential efficacy and toxicity of low-dose granulocyte macrophage colony-stimulating factor (GM-CSF), interleukin 2 (IL-2) and interferon alpha (IFN) postoperatively in patients with highrisk renal cell carcinoma (RCC) . Prostate cancer (PC) is a form of cancer that starts in the prostate gland. Studies suggest that the prostate cancer incidence increased in Asian population in the last few years [51-55]. In HIV-1 infection, some genetic factors may be important as for example the gene variants, encode chemokine receptors: CCR5, CCR2 and CXCR4 - SDF-1 ligand receptor. The finding might be helpful for epidemiological researches of HIV infections and other diseases like diabetes . Asthma and chronic obstructive pulmonary disease (COPD) show resemblance and significant differences. This is specified that asthma and COPD have mutual genetic and environmental risk factors which eventually lead to clinical disease depending on the timing and type of environmental exposures. The genetic predisposition to certain pathways may further help to define the development of COPD. At the end this may lead to stratification of patients by their genetic make-up and open new therapeutic prospects. Juvenile Myelomonocytic Leukemia (JMML) is a serious chronic leukemia which affects young children. Myeloproliferative/myelodysplastic (MPD/MDS) hematopoietic disorder caused by progressive bone marrow failure. Metabolic syndrome is represented as a cluster of conditions, increased blood pressure multiple risk factors, counting central obesity, hypertension and weaken glucose tolerance, that enhances cardiovascular disease morbidity and mortality [57-59]. Ovarian cancer is the fourth leading cause of cancer-related death in women and also the leading cause of gynecologic cancer death. More specifically, epithelial ovarian cancer (EOC) is characterized by few symptoms, display at an advanced stage and poor survival. Many cases around 190,000 new cases of epithelial ovarian cancer (EOC) each year worldwide and this malignancy represents the leading cause of death from gynecological cancers. Possibility of using ANXA7 as both a clinically relevant indicator of disease progression and a prognostic biomarker for survival in the patients with ovarian cancer . Chronic infantile neurological cutaneous and articular syndrome (CINCA), also known as neonatal-onset multisystem inflammatory disease (NOMID), is dominantly-inherited systemic auto inflammatory disease. Some Neuroendocrine tumours (NET) occur in hereditary-familial neoplastic syndromes such as MEN (multiple endocrine neoplasias) or neuroectodermic dysplasias while others arise as solitary-isolated neurofibroma . HNF1B nephropathy is typically responsible for bilateral renal cystic hypodysplasia in childhood one findings have provided data that are useful for recognition and diagnosis of HNF1B disease in adulthood and might help in renal management and genetic counseling [62,63]. Genetic defects of platelet function give rise to mucocutaneous bleeding of varying severity because platelets fail to fulfill their haemostatic role after injury in vessel . Mendelian inheritance has been demonstrated for some disorders while others are associated with mutations and polymorphisms in susceptibility genes . If stable gene transfer is needed, non-integrating vector systems may be combined with transposon-or phage integrase-based systems or future site-specific systems to achieve integration into the host B cell genome . First time a de novo chromosomal abnormality which produced the phenotype of a female with primary ovarian failure and subsequent osteopenia in early adult life . Mutations in several multidrug resistance proteins (MRPs) are associated with human genetic disorders . Dravet syndrome, also called severe myoclonic epilepsy of infancy (SMEI), is a severe form of epilepsy. It appears during the first year of life with frequent febrile seizures. The Dravet syndrome also known as Severe Myoclonic Epilepsy of Infancy (SMEI) begins in the first year of life is a rare and catastrophic form of intractable epilepsy . Fanconi Anemia (FA) is a genetic disease in cancer research, and the most reported of the rare inherited bone marrow failure syndrome . Genetic, hormonal and life-style related factors determine SHBG levels and low sex hormone-binding globulin levels are a known risk factor for the development of the metabolic syndrome, diabetes and cardiovascular diseases .
During the past few years, experimental evidence has emerged to suggest that environmental factors may influence cellular proliferation attrition in an organ-specific manner. These cases, and in disorders there is no genetic background but environmental factors appear to influence and/ or cause disease onset, progression, and outcome . Traditional risk factors for breast cancer explain only a fraction of cases. Source for tendency in breast cancer incidence are not fully comprehended. Breast cancer incidence and mortality rates decrease with environmental conditions that promote Vitamin D synthesis in human skin including lower latitude and higher personal exposure to sunlight . Environmental factors are threats to health and managing them is public environmental health. They include .

Beforehand, It has been accounted for that ordinary ovaries need neutrophil gelatinase related lipocalin (NGAL) articulation and that NGAL statement happens in kindhearted tumors
and increments in ahead of schedule evaluation ovarian tumors . Constant subcutaneous insulin mixture (CSII) treatment is generally acknowledged for fragile sort 1 diabetes, since it has the advantage of less recurrence of hypoglycemia and better administration of the sunrise wonder contrasted with different day by day insulin infusion (MDI) treatment . Near studies in the middle of African and European populaces recommend that aggregate lymphocyte check (TLC), including CD4+ number, is liable to fluctuate essentially by ethnicity, in both, solid and HIV-contaminated Individuals . Common executioner (NK) cell capacity was researched in Malaysian HIV patients starting antiretroviral treatment (ART) with cutting edge immunodeficiency. A few patients experienced resistant reclamation illness (IRD) displaying as intensifications of previous diseases. Whilst most IRD are credited to interferon-gamma created by T-cells, NK cells might likewise contribute . As of late specific consideration has been attracted to the impact of antiretroviral (ARV) treatments on the rate of genuine non-AIDS occasions (SNAEs), including cardiovascular infection (CVD), end-stage renal ailment, liver disappointment and breaks specifically noteworthy is the impact of individual ARVs or ARV classes on these occasions . Insusceptible Recovery Inflammatory Syndrome (IRIS) is described by a confusing disintegration of clinical status after launch of Anti- Retroviral Therapy (ART), regardless of enhanced resistant capacity. It is brought about by provocative reaction against the irresistible antigen . It takes after an already asymptomatic man who gave normal, non-particular manifestations and was diagnosed with an uncommon confusion of non-typhi Salmonella contamination. This serves as an unmistakable suggestion to all clinicians to have a low limit for testing for HIV and highlights the need to present a withdraw framework for HIV testing in all intense medicinal services settings with a high commonness of HIV contamination . Attendant antiretroviral treatment (ART) can be a component prompting a lower adequacy of pegylated interferon (peg-IFN) in addition to ribavirin (RBV) in human immunodeficiency infection (HIV)/hepatitis C infection (HCV)- confected patients. In this study, HIV/HCV-confected patients who were treated with a three-medication regimen including TDF in addition to 3TC or FTC alongside NVP reacted better to peg-IFN in addition to RBV than the individuals who took LPV/r, a finding that has not been beforehand reported . Indeed, even with mix antiretroviral treatment (cART) regimen, the solidness of HIV control is constrained by numerous components (adherence to treatment, drug harmfulness, bioavailability, among the most essential. At the point when rescue treatment is viewed as, better result is normal if antiretroviral regimen incorporates a class to which the patient has not been uncovered beforehand. Thusly classes of antiretroviral medications coordinated at targets other than converse transcriptase or protease are of potential extraordinary interest . Studies planned to evaluate the impacts of medications in patients with safe disappointment, and in addition on the frequency on AIDS and non-AIDS occasions, liver fibrosis and atherosclerosis movement are unmistakably required . Histoplasma is a dimorphic pathogenic growth which causes human disease around the world, for the most part in central nations . Irresistible creatures, probably infections, have long been a suspect for setting off the immune system reaction in individuals hereditarily defenseless to MS.
