Abstract
Dementia is a multifactorial disease in which environmental, lifestyle, and genetic factors intervene. Population studies have been used in looking for the susceptibility genes for this disease. Since the activity of dopamine b hydroxylase (DβH) is reduced in the hippocampus and neocortex in the brain, changes in the physiological status of dopamine have been reported in Alzheimer's disease (AD) induced by this enzyme. Therefore, DBH polymorphisms have been associated with susceptibility to some neurological diseases such as AD, but few studies have investigated the relationship between these polymorphisms with other types of dementia, especially in Mexican populations. The aim of this study was to evaluate the association between single-nucleotide polymorphism (SNP) in the dopamine b-hydroxylase (DBH gene (rs1611115) and their interactions with environmental factors and the dementia risk. We examined the genotype of the gene DBH (rs1611115) polymorphism in patients with dementia and healthy. The interaction and the impact of DBH (rs1611115) polymorphism on dementia were examined through multifactor dimensionality reduction (MDR) analysis, and the results were verified by the Chi-square test. Hardy-Weinberg equilibrium (HWE) was also checked by the Chi-square test. The relative risk was expressed by odds ratio (OR) and 95%. A total of 221 dementia patients and 534 controls met the inclusion criteria of MDR analyses. The results of the MDR analysis showed that the development of dementia was positively correlated with interaction between the TT genotype of the DBH1 locus rs1611115 TT and diabetes, hypertension, and alcohol consumption (OR = 6.5: 95% CI = 4.5-9.5), originating further cognitive damage. These findings provide insight into the positive correlation between the metabolism and cardiovascular disorders and the presence of the T allele by means of a recessive model of DBH rs1611115 polymorphism with the suspensibility of dementia.

Abstract
OBJECTIVE Evidence supports the important role of neuroinflammation in some types of dementia. This study aimed to evaluate the effect of epistasis of gene cytokines such as interleukin (IL)-α, IL-6, tumor necrosis factor (TNFα), and interferon-gamma (IFN-γ) on the susceptibility to the development of dementia. MATERIALS AND METHODS In the study, 221 patients diagnosed with dementia and 710 controls were included. The multifactor-dimensionality reduction (MDR) analysis was performed to identify the epistasis between SNP located in genes of IL-α (rs1800587), IL-6 (rs1800796), TNFα (rs361525 and rs1800629), and IFNγ (rs2069705). The best risk prediction model was identified based on precision and cross-validation consistency. RESULTS Multifactor-dimensionality reduction analysis detected a significant model with the genes TNFα, IFNγ, IL1α, and IL6 (prediction success: 72%, p < 0.0001). When risk factors were analyzed with these polymorphisms, the model achieved a similar prediction for dementia as the genes-only model. CONCLUSION These data indicate that gene-gene interactions form significant models to identify populations susceptible to dementia.

Abstract
There is an inconsistent finding about the relationship of catechol-O-methyltransferase (COMT) with dementia susceptibility, as well as with cognitive impairment. To substantiate this, we examined COMT genotype effects in certain cognitive domains in dementia. To evaluate the effects of COMT Val158Met on cognitive performance, we used The Mini-Mental State Examination (MMSE), the cognitive subscale of the Alzheimer's Disease Assessment Scale-cognitive (ADAS-cog) and the Syndrome Kurz Test (SKT). The results show COMT Val/Met, Val/Val genotype polymorphisms had a significant effect on cognition performance (OR = 1.75 (95 %CI 1.22-2.54) and (OR = 2.76 (95 %CI 1.78-4.26), p < 0.001), and with adjustment for all cognitive test scores together, Val/Val (OR = 4.98 (95 % CI 1.47-16.86) and Val/Met (OR = 3.62 (95 % CI 1.37-9.56) had effect. Our study allows us to understand the role of COMT in cognitive performance in dementia, as well as interaction with other known risk factors for this pathology. This data might help in developing new therapeutic targets for cognitive impairment, main symptom of dementia. Other risk genotypes or haplotypes should be evaluated to determine the association with cognitive decline in dementia.

Abstract
BACKGROUND Cognitive functions represent useful endophenotypes to identify the association between genetic variants and schizophrenia. In this sense, the NR4A2 gene has been implicated in schizophrenia and cognition in different animal models and clinical trials. We hypothesized that the NR4A2 gene is associated with working memory performance in schizophrenia. This study aimed to analyze two variants and the expression levels of the NR4A2 gene with susceptibility to schizophrenia, as well as to evaluate whether possession of NR4A2 variants influence the possible correlation between gene expression and working memory performance in schizophrenia. METHODS The current study included 187 schizophrenia patients and 227 controls genotyped for two of the most studied NR4A2 genetic variants in neurological and neuropsychiatric diseases. Genotyping was performed using High Resolution Melt and sequencing techniques. In addition, mRNA expression of NR4A2 was performed in peripheral mononuclear cells of 112 patients and 118 controls. A group of these participants, 54 patients and 87 controls, performed the working memory index of the WAIS III test. RESULTS Both genotypic frequencies of the two variants and expression levels of the NR4A2 gene showed no significant difference when in patients versus controls. However, patients homozygous for the rs34884856 promoter variant showed a positive correlation between expression levels and auditory working memory. CONCLUSIONS Our finding suggested that changes in expression levels of the NR4A2 gene could be associated with working memory in schizophrenia depending on patients' genotype in a sample from a Mexican population.

Abstract
Background: Dementia is a persistent, progressive state of cognitive decline against which pharmacological intervention has a modest efficacy, reducing behavioral but not cognitive symptoms. Therefore, different non-pharmacological therapies have been developed; the most scientifically recognized are cognitive therapies that have improved cognitive function and daily life activities. Objective: To evaluate the effectiveness of a multicomponent cognitive stimulation therapy (SADEM) on cognitive and behavioral function and daily life activities in patients with mild stage dementia. Methods: Controlled clinical trial with pre- and post-intervention (12 months) and follow-up (24 months after) evaluations. Participants (67) diagnosed with mild dementia were randomly assigned to intervention group (n = 39) or control group (n = 28). The intervention took place throughout one year and consisted of two weekly 90-minute sessions and one more a year after a monthly follow-up. Instruments were used to evaluate outcomes in cognitive, behavioral, and affective domains. Results: The results showed statistically significant differences, with improvement in the cognitive outcomes and the Dementia Index post-intervention (p = 0.01). No progression of the disease was observed at the end of the study. Conclusion: The multicomponent intervention tested had positive effects on cognitive and behavioral functions and daily life activities in people with mild stage dementia, delaying progression for at least two years.

Abstract
One of the hypotheses that have emerged to explain the origin of dementia relates the disease with altered lipid metabolism, particularly cholesterol. To maintain cholesterol homeostasis, the ACAT1 enzyme has an important function to regulate the production of Aβ. Moreover, APOE is the main cholesterol carrier in the brain, and it has been reported as a risk factor for this disease. This study evaluates the relationship between ACAT1 and APOE genetic variants with susceptibility for the development of Alzheimer's disease and other dementias. We examined four ACAT1 polymorphisms (rs2247071, rs2862616, rs3753526, rs1044925) and two in the APOE gene (rs7412, rs429358) in a group of 204 controls and 196 cases of dementia. Our results show one protective haplotype: CGCA (OR = 0.34, 95% CI = 0.23-0.46; p < 0.001) and one risk haplotype: CGGA (OR = 1.87, 95% CI = 1.34-2.60; p < 0.001) for the development of dementia. Subjects identified as APOE-ε4 allele carriers had a higher risk of developing dementia compared with non-carriers, OR = 13.33 (95% CI = 3.14-56.31). The results support the hypothesis that the ACAT1 gene, together with the APOE gene, plays an important role in susceptibility to the development of dementia and shows genetic characteristics of the Mexican population that can be used to identify the population at risk.

Abstract
INTRODUCTION The NR4A2 transcription factor is important in the development, survival and phenotype of dopaminergic neurons and it is postulated as a possible biomarker for Parkinson's disease (PD). Therefore, our aim was to analyze in a sample of a Mexican population with idiopathic PD, mutations (in two hotspot mutation regions) and two polymorphisms (rs34884856 in promotor and rs35479735 intronic regions) of the NR4A2 gene. We also evaluate the levels of NR4A2 gene expression in peripheral blood for a Mexican population, and identify whether they are associated with NR4A2 gene polymorphisms. METHODS We conducted a case-control study, which included 227 idiopathic PD cases and 454 unrelated controls. Genetic variants of the NR4A2 gene were genotyped by high-resolution melting (HRM) and validated by an automated sequencing method. The gene expression was performed in peripheral blood using a real-time polymerase chain reaction. RESULTS The rs35479735 polymorphism was associated with a higher risk of developing PD. In addition, NR4A2 gene expression was significantly decreased in patients with PD. Linkage disequilibrium analysis showed a haplotype H4 (3C-3G) that showed lower levels of expression, and contained the risk alleles for both polymorphisms. CONCLUSIONS In summary, this is the first study in a Mexican population that considers the analysis of NR4A2 in patients with PD. An association was identified between genotype and mRNA expression levels of NR4A2 in patients with PD. These results suggest that polymorphisms and expression of the NR4A2 gene could play an important role in the risk of developing PD in Mexican populations.

Abstract
Objective The objective is to present a clinical case of a 38-year-old male with a maxillary unicystic ameloblastoma treated by means of tumor block resection followed by chin-harvested graft placement in order to place two dental implants for esthetic and functional rehabilitation. Methods Ameloblastoma is a benign odontogenic tumor characterized by local aggression and a high rate of recurrence; the latter partly depends on how it is treated. Complete resection of the tumor, which usually prevents recurrence, produces bone defects of varying size that must be reconstructed later on. In most cases this is done using bone grafts and implant-supported prostheses. Grafts harvested from the chin are relatively easy to obtain and enjoy a fairly uneventful post-operative with few complications; they are suitable for cases in which the defect generated by resection is of small size. Results Functional and esthetic rehabilitation and the tumor has not relapsed during a 7-year follow-up. Conclusion Tumor block resection followed by chin-harvested graft placement and dental implants is a safe treatment for patients with unicystic ameloblastoma.

Abstract
Some studies have reported a genetic association between single nucleotide polymorphisms (SNPs) in the promoter region of Interleukin (IL) 10 and Alzheimer's disease (AD), with conflicting results. To further investigate the proposed association and to clarify the role of cytokines as a potential cause for AD susceptibility, we analyzed genotypes, allele distributions and haplotypes of IL-10 promoter polymorphisms -1082 (rs1800896) and -819 (rs1800871) in a Mexican population: 986 normal controls and 221 cases divided as follows: 122 with Alzheimer disease (AD), 67 with (VaD) and 32 with mixed dementia (AD/VaD). Patients with dementia showed increased frequency of "ATA, CTG, and CTA" haplotypes when compared to controls. We identified two risk haplotypes: ATA (OR=3.56, 95%CI=2.84-4.45, p<0.0001), and CTA (OR=1.90, 95%CI=1.38-2.62, p<0.0001), and four protection haplotypes: ATG (OR=0.60, 95%CI=0.45-0.82, p=0.0012), CTG (OR=0.38, 95%CI=0.23-0.62, p<0.0001), ACG (OR=0.01, 95%CI=0.002-1.13, p<0.0001), and CCG (OR=0.02, 95%CI=0.004-0.203, p<0.0001). In summary, this is the first study in Mexican population that considers the analysis of IL-10 in patients with AD, VaD and AD/VaD. Our results showed the relevance of the role that IL-10 plays in the pathological mechanisms that result in the development of dementia. In addition, in our study, it was possible to distinguish two protective and two risk haplotypes for the development of dementia.

Abstract
To compare the distribution of HLA-A, B, DRB1 and DQB1 alleles among Mexican patients with primary Sjögren Syndrome (pSS), secondary SS (sSS), connective tissue disease (CTD) without (w/o) SS and historical ethnically healthy controls. We included 28 pSS, 30 sSS, 96 CTD w/o SS patients and 234 controls. HLA-A, B, DRB1 and DQB1 were amplified and sequenced using the Allele SEQR Sequenced Based Typing Kits and analyzed on the ABI Prism*3130 DNA Analyzer using the Assign software. Gene frequencies were obtained by direct counting. Contingence tables of 2 × 2 were generated and analyzed by the Mantel-Haenzel χ (2) or Fisher's test (EPIINFO program). We reported odds ratios (OR) and corrected p values. SS patients showed increased frequencies of A*68:01 and DRB1*14:06 alleles when compared to CTD w/o SS (OR 4.43, 95 % CI 1.35-14.14, p = 0.007 and OR 14, 95 % CI 1.68-116, p = 0.001, respectively) and a higher prevalence of DRB1*01:01 (OR 5.9, 95 % CI 2.13-16.56, p = 0.003) and HLA-B*35:01 (OR 3.70, 95 % CI 1.92-7.12, p = 0.004) when compared with controls. pSS patients had a higher frequency of DRB1*14:06 allele than sSS (OR 16, 95 % CI 1.59-390, p = 0.001). Anti-Ro/SSA positivity was associated with B*51:01 (OR 10.11, 95 % CI 1.09-245, p = 0.02) and DRB1*03:01 alleles (OR 4.26, 95 % CI 1.01-18.89, p = 0.029), whereas the A*01:01 allele was associated with anti-La/SSB positivity (OR 4.75, 95 % CI 1.32-16.92, p = 0.003). In our population, the DRB1*14:06 allele was associated with primary and secondary SS implying that both varieties bear a similar immunogenetic background.

Abstract
The aim of the present study was to establish the role of ACE gene polymorphisms in the risk of developing in-stent restenosis and/or coronary artery disease (CAD). Eight ACE gene polymorphisms were genotyped by 5' exonuclease TaqMan genotyping assays in 236 patients with CAD who underwent coronary artery stenting. Basal and procedure coronary angiographies were analyzed searching for angiographic predictors of restenosis and follow-up angiography was analyzed looking for binary restenosis. A group of 455 individuals without clinical and familial antecedents of cardiovascular diseases were included as controls. Haplotypes were constructed after linkage disequilibrium analysis. Distribution of ACE polymorphisms was similar in patients with and without restenosis. Similar results were observed when the analysis was made comparing the whole group of patients (with and without restenosis) and healthy controls. Six out of eight polymorphisms were in high linkage disequilibrium and were included in five haplotypes (AAAGCA, GGGATG, GAGATG, AGAGCA and AAGACA). The distribution of these haplotypes was similar in patients with and without restenosis. However, CAD patients showed an increased frequency of the AAAGCA haplotype (OR=1.31, 95% CI: 1.04-1.66, P=0.018) and decreased frequencies of GAGATG (OR=0.47, 95% CI: 0.25-0.88, P=0.011) and AGAGCA (OR=0.15, 95% CI: 0.02-0.65, P=0.002) haplotypes when compared to healthy controls. Haplotypes of the ACE gene could be a genetic factor related to coronary artery disease in the Mexican individuals, but do not support its role as a risk factor for developing restenosis after coronary stenting.

Abstract
The aim of the present study was to establish the role of HIF1A gene polymorphisms in the risk of developing premature coronary artery disease (CAD) in a well-characterized clinical cohort. Three polymorphisms in HIF1A (rs11549465, rs11549467, rs2057482) gene were genotyped in 949 patients with premature CAD, and 676 healthy controls (with negative calcium score by computed tomography). Under a dominant model adjusted for age, visceral to subcutaneous adipose tissue (VAT/SAT) ratio, hypertension, type 2 diabetes mellitus (T2DM), HDL-C levels, hypercholesterolemia and hypertriglyceridemia, the rs2057482 T allele was associated with decreased risk of premature CAD when compared to healthy controls (OR = 0.616, P(dom) = 0.020). The effect of the studied polymorphisms on various metabolic parameters and cardiovascular risk factors was explored. In this analysis, the rs2057482 T allele was associated with decreased risk of obesity, central obesity, hypertension, hypercholesterolemia, hypertriglyceridemia and increased risk of T2DM. Under a dominant model adjusted by age, the HIF1A rs2057482 T polymorphism was associated with high VAT/SAT ratio (P = 0.009) and HDL-C levels (P = 0.04) in healthy controls. The results suggest that HIF1A rs2057482 polymorphism is involved in the risk of developing CAD and is associated with some metabolic parameters and cardiovascular risk factors.

Abstract
Matrix metalloproteinases (MMP) are enzymes that degrade extracellular matrix (ECM) proteins and regulate both their accumulation and composition. The MMP are involved in the atherosclerotic process since they contribute to the formation of the plaque and its subsequent rupture. This last step triggers the myocardial ischemia that will be clinically reflected as an acute coronary syndrome (ACS). Thus, MMP activity is a key to whether ACS develops or not. With an elevated transcription rate of the genes that codify these proteinases comes a higher enzymatic activity. This explains that if a polymorphism in the mentioned genes modifies transcription, there could be a predisposition to developing ACS. Several studies reveal that certain genetic variations in MMP-1, -2, -3, -7, -8, -9, -12, and -14 have an important role either as risk factors or as protective factors for the expression of ACS.

Abstract
AIM To explore the role of the ACE gene polymorphisms in the risk of essential hypertension in Mexican Mestizo individuals and evaluate the correlation between these polymorphisms and the serum ACE levels. METHODS Nine ACE gene polymorphisms were genotyped by 5' exonuclease TaqMan genotyping assays and polymerase chain reaction (PCR) in 239 hypertensive and 371 non- hypertensive Mexican individuals. Haplotypes were constructed after linkage disequilibrium analysis. ACE serum levels were determined in selected individuals according to different haplotypes. RESULTS Under a dominant model, rs4291 rs4335, rs4344, rs4353, rs4362, and rs4363 polymorphisms were associated with an increased risk of hypertension after adjusting for age, gender, BMI, triglycerides, alcohol consumption, and smoking. Five polymorphisms (rs4335, rs4344, rs4353, rs4362 and rs4363) were in strong linkage disequilibrium and were included in four haplotypes: H1 (AAGCA), H2 (GGATG), H3 (AGATG), and H4 (AGACA). Haplotype H1 was associated with decreased risk of hypertension, while haplotype H2 was associated with an increased risk of hypertension (OR = 0.77, P = 0.023 and OR = 1.41, P = 0.004 respectively). According to the codominant model, the H2/H2 and H1/H2 haplotype combinations were significantly associated with risk of hypertension after adjusted by age, gender, BMI, triglycerides, alcohol consumption, and smoking (OR = 2.0; P = 0.002 and OR = 2.09; P = 0.011, respectively). Significant elevations in serum ACE concentrations were found in individuals with the H2 haplotype (H2/H2 and H2/H1) as compared to H1/H1 individuals (P = 0.0048). CONCLUSION The results suggest that single nucleotide polymorphisms and the "GGATG" haplotype of the ACE gene are associated with the development of hypertension and with increased ACE enzyme levels.

Abstract
Heart development consists in a group of complex and specific morfogenetic interactions, that requires the proper activity of each factor implicated in this process. Congenital heart defects (CHD) are a group of multifactorial complex diseases with environmental and genetic factors playing important roles. There is not an exact relation between molecular mechanisms and morphological defects in CHD, because in most of the cases the proper development of an anatomical structure implies the adequate function of several pathways that may depend of the action of different genes. This review summarizes the genetic factors implied in the normal heart development and the most common gene mutations associated with CHD.

Abstract
AIM Was to evaluate the role of seven matrix metalloproteinase (MMP) polymorphisms in the genetic susceptibility to develop myocardial infarction in Mexican individuals. METHODS Seven polymorphisms in the MMP genes were genotyped by 5' exonuclease TaqMan genotyping assays in 300 patients with myocardial infarction and 300 healthy unrelated controls. RESULTS A similar distribution of MMP2-1306 (rs243865), MMP2-790 (rs243864), MMP2-735 (rs22850553), MMP7-153(rs11568819), MMP7-181(rs11568818), and MMP12-82(rs2276109) polymorphisms was observed in both studied groups. On the other hand, patients showed increased frequencies of MMP2-1575 A allele and AA genotype when compared to controls (pC= 0.001; OR= 1.58 and pC= 0.036; OR= 2.37, respectively). According to the dominant model, individuals with AG+AA genotypes had a 1.65-fold increased risk of developing the disease (p= 0.002). After adjusting for known risk factors, we found a significant contribution of gender, BMI, smoking habit, diabetes mellitus, and hypertension to the inheritance model. In this analysis, individuals with the-1575 AA genotype had a 4.23-fold increased risk of developing MI (p= 0.003). On the other hand, an association of the MMP12-82 polymorphism with the extent of coronary artery disease (CAD) was observed. In our study, it was possible to distinguish two risk haplotypes and one protective haplotype for this disease in the MMP2 gene. CONCLUSIONS The results suggest that the MMP2-1575 (rs243866) gene polymorphism could be involved in the risk of developing myocardial infarction in Mexican individuals.

Abstract
OBJECTIVES To evaluate the anaesthetic properties and tolerance of articaine versus lidocaine at equal vasoconstrictor concentration. STUDY DESIGN A total of 96 male and female patients who underwent surgical treatment of the lower third molar participated. Patients were randomly assigned to articaine hydrochloride with epinephrine 1:100,000 and lidocaine hydrochloride with epinephrine 1:100,000. The variables analysed were latency period, duration of anaesthetic effect, tolerance and adverse reactions. RESULTS Both the latency period and the duration of anaesthetic effect were greater for articaine, although the differences were not statistically significant. Latency: mean difference of 2.70 ± 2.12 minutes (95%CI of -1.51 minutes - 6.92 minutes). DURATION mean difference of -33 minutes 5 seconds ± 31 minutes (95% CI -1 hour 35 minutes - 29 minutes). There were 4 adverse events that did not require the patients to be withdrawn from the study. CONCLUSIONS The anaesthetics in this study have very similar properties for use in surgery and have demonstrated a good safety and tolerability profile.

Abstract
INTRODUCTION Hypertension is a complex disease in which a significant interaction between genetic and environmental factors takes place. The renin-angiotensin system plays an important role regulating blood pressure to maintain homeostasis and vascular tone. In the present work, the role of angiotensin II type 1-receptor (AGTR1) gene polymorphisms as susceptibility markers for hypertension was evaluated. MATERIALS AND METHODS Five polymorphisms in the AGTR1 gene were genotyped by 5' exonuclease TaqMan genotyping assays in 239 hypertensive and 371 non-hypertensive individuals. RESULTS A similar distribution of rs275651, rs275652, rs275653, and rs5183 polymorphisms was observed in both studied groups. Different distribution of rs5182 genotypes was observed between the studied groups (p = 0.016). According to the co-dominant model, individuals with rs5182 CC genotype have a 1.83-fold increased risk of developing hypertension (p = 0.009). Polymorphisms were distributed in two blocks: block 1 included the rs275651, rs275652, and rs275653 polymorphisms, whereas block 2 included the rs5183 and rs5182 polymorphisms. Individuals with hypertension showed increased frequency of 'CA' haplotype of block 2 when compared to non-hypertensive individuals (p = 0.015, odds ratio = 1.33). CONCLUSION The results suggest that the rs5182 gene polymorphism could be involved in the risk of developing hypertension in Mexican individuals.

Abstract
Inflammation is the primary response to vessel wall injury caused by stent placement in coronary arteries. Cytokines of the interleukin-1 family are central regulators in immunoinflammatory mechanisms. The objective of this study was to test for association between IL-1 family gene polymorphisms and risk for restenosis after coronary stent placement. The IL-1B-511, IL-1F10.3, RN.4T>C, RN.6/1C>T, RN.6/2C>G, and IL-1RN VNTR polymorphisms were analyzed by 5' exonuclease TaqMan genotyping assays and polymerase chain reaction in a group of 165 patients who underwent coronary artery stenting. Basal and procedure coronary angiography were analyzed in search of angiographic predictors of restenosis and follow-up angiography was analyzed in search of binary restenosis. Patients with IL-1B-511 TT genotype had a 1.89-fold increased risk of developing restenosis. The analysis considering the lesions treated demonstrated that the lesions of patients with IL-1B-511 TT genotype had a 3.44-fold increased risk of developing restenosis. When the analysis considered the type of stent, the risk of developing restenosis was increased in lesions of patients with TT genotype (odds ratio = 4.50) who underwent coronary bare-metal stent implantation. Multiple logistic analysis identified IL-1B-511 TT genotype as an independent predictor for restenosis. The results suggest that IL-1B-511 polymorphism could be involved in the risk of developing restenosis after coronary stent placement.

Abstract
The purpose of the present study was to evaluate the relationship between class II major histocompatibility complex (MHC) genes (HLA-DR and HLA-DQB) and the genetic susceptibility to idiopathic dilated cardiomyopathy (IDC) in Mexican patients. The HLA-DR and DQB alleles were analyzed in 53 patients with IDC and 99 ethnically matched healthy controls using the polymerase chain reaction-sequence specific oligonucleotides (PCR-SSO) technique. IDC patients showed increased frequencies of HLA-DR4 (pC=0.02, OR=1.87), HLA-DQB1*0301 (pC=0.02, OR=1.92) and HLA-DQB1*0302 (pC=0.02, OR=1.87) when compared to healthy controls. On the other hand, IDC patients also showed decreased frequencies of HLA-DR11 allele (pC=0.03, OR=0.26) and HLA-DQB1*0201 (pC=0.04, OR=0.41). These data suggest that variation in class II HLA alleles could be a genetic factor involved in the susceptibility to IDC of the Mexican Mestizo population.

Abstract
The beta1 adrenergic receptor genotypes (Ser49Gly and Arg389Gly) were determined in 190 individuals from 3 Mexican populations. Mestizos and Teenek present the highest frequencies for the *Arg allele and the lowest frequencies for the *Gly allele (Arg389Gly) compared to European, Asian, and African populations. Mayos present the highest frequency for the *Gly allele. The knowledge of the distribution of these alleles could help define the significance of these polymorphisms as genetic susceptibility markers in Amerindian populations.

Abstract
Matrix gamma-carboxyglutamic acid protein (MGP) genotypes (G-7A and T-138C) were determined in 266 individuals from three Mexican populations. Mexicans showed increased frequencies of the G-7A G allele and the G7-A GG genotype compared to Europeans. For the T-138C genotype, we found differences among the Mexicans. This study could help to define the significance of MGP polymorphisms as genetic markers in Amerindian populations.
