Abstract
Suicide is defined as the action of harming oneself with the intention of dying. It is estimated that worldwide, one person dies by suicide every 40 s, making it a major health problem. Studies in families have suggested that suicide has a genetic component, so the search for genetic variants associated with suicidal behavior could be useful as potential biomarkers to identify people at risk of suicide. In Mexico, some studies of gene variants related to neurotransmission and other important pathways have been carried out and potential association of variants located in the following genes has been suggested: SLC6A4, SAT-1, TPH-2, ANKK1, GSHR, SCARA50, RGS10, STK33, COMT, and FKBP5. This systematic review shows the genetic studies conducted on the Mexican population. This article contributes by compiling the existing information on genetic variants and genes associated with suicidal behavior, in the future could be used as potential biomarkers to identify people at risk of suicide.

Abstract
The correlation of early life adversity with adulthood psychopathology has already been revealed by epidemiological studies. To find the biological mechanisms underlying the cross-talk between prenatal adversity and mental health, molecular genetic studies have been performed using animal models of prenatal undernutrition and stress, reporting altered expression of serotonin receptors which modulate the release of many neurotransmitters that regulate a broad range of physiological functions including psychopathology. Unfortunately, no such study has been possible on humans due to ethical reasons. Using the Chinese Famine of 1959-1961 as a natural experiment, we investigated DNA methylation patterns in genes of the serotonin receptor signaling pathway in the whole blood of adults born during the famine. A significant pattern of reduced DNA methylation was observed in sex combined samples (p value, 0.022). In a sex-stratified analysis, the pattern was only significant in females (p-value, 0.019) but not in males. We further tested the DNA methylation patterns specifically in HTR1A, HTR2A and the X-linked HTR2C and found reduced DNA methylation in females for HTR2A (p-value 0.033) and HTR2C (p-value 0.014) but not in males. Overall, this study reveals altered epigenetic regulation of the serotonin receptor signaling pathway in association with prenatal adversity in humans providing novel epigenetic evidence in support of neurodevelopmental origin of psychiatric disorders.

Serotonin Receptor Gene Polymorphisms Are Associated with Cerebrospinal Fluid, Genetic, and Neuropsychological Biomarkers of Alzheimer's Disease. Biomedicines 2022; 10:biomedicines10123118. [PMID: 36551873 PMCID: PMC9775360 DOI: 10.3390/biomedicines10123118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 11/26/2022] [Accepted: 11/30/2022] [Indexed: 12/12/2022] Open
Abstract
A decrease in serotonergic transmission throughout the brain is among the earliest pathological changes in Alzheimer's disease (AD). Serotonergic receptors are also affected in AD. Polymorphisms in genes of serotonin (5HT) receptors have been mostly associated with behavioral and psychological symptoms of dementia (BPSD). In this study, we examined if AD patients carrying different genotypes in 5HTR1B rs13212041, 5HTR2A rs6313 (T102C), 5HTR2C rs3813929 (-759C/T), and 5HTR6 rs1805054 (C267T) polymorphisms have a higher risk of faster disease progression (assessed by neuropsychological testing), are more prone to develop AD-related pathology (reflected by levels of cerebrospinal fluid [CSF] AD biomarkers), or have an association with an apolipoprotein E (APOE) haplotype. This study included 115 patients with AD, 53 patients with mild cognitive impairment (MCI), and 2701 healthy controls. AD biomarkers were determined in the CSF of AD and MCI patients using enzyme-linked immunosorbent assays (ELISA), while polymorphisms were determined using either TaqMan SNP Genotyping Assays or Illumina genotyping platforms. We detected a significant decrease in the CSF amyloid β1-42 (Aβ1-42) and an increase in p-tau181/Aβ1-42 ratio in carriers of the T allele in the 5HTR2C rs3813929 (-759C/T) polymorphism. A significantly higher number of APOE ε4 allele carriers was observed among individuals carrying a TT genotype within the 5HTR2A T102C polymorphism, a C allele within the 5HTR1B rs13212041 polymorphism, and a T allele within the 5HTR6 rs1805054 (C267T) polymorphism. Additionally, individuals carrying the C allele within the 5HTR1B rs13212041 polymorphism were significantly more represented among AD patients and had poorer performances on the Rey-Osterrieth test. Carriers of the T allele within the 5HTR6 rs1805054 had poorer performances on the MMSE and ADAS-Cog. As all four analyzed polymorphisms of serotonin receptor genes showed an association with either genetic, CSF, or neuropsychological biomarkers of AD, they deserve further investigation as potential early genetic biomarkers of AD.

Abstract
Five polymorphisms (rs4713916, rs4713902, rs1360780, rs9296158 and rs3800373) of FKBP5 gene were analyzed in a case-control study comprising 423 Mexican individuals (146 individuals with suicide attempt and 277 controls). The SNP's were genotyped using the TaqMan-allelic assay. Genotype and allele frequencies were compared between the two groups, then the association between FKBP5 gene polymorphisms and suicide attempt was analyzed. We found a significant association of rs1360780 T minor allele (All, OR = 1.80, 95 % CI = 1.35-2.41, P = 0.0005; Males, OR = 2.25, 95 % CI = 1.44-3.50, P = 0.0002) as a suicide behavior risk factor. Conversely, rs3800373 C minor allele (All, OR = 0.61, 95 % CI = 0.46-0.83; P = 0.0013; Females, OR = 0.33, 95 % CI = 0.22-0.50; P = 0.0001) and the A-C-T-A-C haplotype (OR = 0.06, 95 % CI = 0.01-0.36; P = 0.002) were significantly associated as protective factors. No association was observed with the other SNP's. Our study suggests that SNP's in FKBP5 gene contribute to suicide behavior pathogenesis.

Gene-level genome-wide association analysis of suicide attempt, a preliminary study in a psychiatric Mexican population. Mol Genet Genomic Med 2019; 7:e983. [PMID: 31578828 PMCID: PMC6900393 DOI: 10.1002/mgg3.983] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2019] [Revised: 08/20/2019] [Accepted: 09/03/2019] [Indexed: 12/11/2022] Open
Abstract
Background Evidence suggests that liability for suicide behavior is heritable; additionally, suicide has been partly related to other psychiatric disorders. Nevertheless, most of the information reported so far address Caucasian and Asian individuals. Hence, our aim was to conduct a gene‐level association study in Mexican psychiatric individuals diagnosed with suicide attempt. Methods We recruited 192 individuals from two clinical centers in Mexico. All participants were born in Mexico and had Mexican parents and grandparents. Direct genotyping was performed using the commercial platform Infinium PsychArray BeadChip. A p‐value lower than 1e‐05 was considered as gene‐level significant and a p‐value lower than 1e‐04 was considered as gene‐level nominal significant. Results Our analyses showed that SCARA5 was associated to suicide intent at a gene‐level with statistical significance (p‐value = 1.12e‐6). Other genes were nominally associated with suicide attempt: GHSR (p‐value = 0.0004), RGS10 (p‐value = 5.13e‐5), and STK33 (p‐value = 3.62e‐5). Regarding gene variant analyses, the SNPs with a statistical association (p > .05) were rs561361616, rs1537577, rs11198999 for RGS10, and rs11041981, rs11041993, rs11041994, rs11041995, rs11041997, rs10840083, rs10769918 for STK33. For these genes, previous studies have associated SCARA5 with depression, GHSR with alcohol dependence and depression, and RGS10 with schizophrenia and depression. To date, STK33 has not been associated with any psychiatric disorder. Conclusion Our outcomes revealed that SCARA5, GHSR, RGS10 and STK33 could be considered as risk biomarkers for suicide attempt behavior in our Mexican psychiatric sample. We recommend to perform larger scale analyses to have conclusive results.
