The trichorhinophalangeal syndrome is a rare genetic disorder with a classical clinical triad of sparse hair, bulbous nose, and short digits. There are three known phenotypes, and the type II with exostoses in long bones is known as Langer-Giedion syndrome. Here, we describe a 28-year-old Sri Lankan male with Langer-Giedion syndrome and high-functioning autism. The karyotype found a microdeletion of the long arm of chromosome 8 with mosaicism [46,XY/46,XY,del(8)(q24.1q24.3)]. This is probably the first report of Langer-Giedion Syndrome with autism and the first report of the genetic syndrome from Sri Lanka...

OBJECTIVE: In recent decades, the role of genetic factors in the predisposition to suicidal behavior has attracted considerable attention. Although each genetic investigation appears to be valuable, no one study on its own can comprehensively explain the etiology of suicidal behavior. METHODS: In this study, using a broad literature review, we found the suicide-associated gene coexpression network. In addition, cytoband, molecular function, biological process, cellular component, tissue-based expression, and disease/disorder enrichment analyses were carried out to determine the most central cellular and molecular infrastructures involved in suicidal behavior...

BACKGROUND: Schizophrenia (SCZ) is a severe and heritable psychiatric disorder, and previous studies have shown that regulation of the forkhead-box P2 gene (FOXP2) may play a role in schizophrenia. Moreover, just a few studies have identified a single nucleotide polymorphism (SNP) rs10447760 within the gene that was a risk variant for SCZ in the Chinese Han population. METHODS: To examine whether the variant in the FOXP2 gene contributes toward SCZ susceptibility, we carried out an association analysis of the SNP rs10447760 of the FOXP2 gene in a case-control study (1405 cases, 1137 controls) from China...

Recently, several studies have investigated the association between the rare mutation of triggering receptor expressed on myeloid cells 2 (TREM2) gene (rs75932628-T) and the risk of late-onset Alzheimer's disease (LOAD), but they did not draw the same conclusion. Our aim was to investigate the link between the TREM2 polymorphism and LOAD in the Chinese Han population. We examined 786 patients and 803 controls in this study. The rs75932628 polymorphism was evaluated using high-resolution melting analysis and direct sequencing...

The objective of this study was to investigate the relationship between methylation patterns of the histone deacetylase 4 gene and eating disorders in a site previously associated with anorexia nervosa (AN). Women with AN (N=28) or bulimia nervosa (BN) (N=19) were age-matched and sex-matched to controls (N=45). We obtained saliva-derived DNA and use bisulfite pyrosequencing to examine region-specific methylation differences between cases and controls. The region assayed includes 15 CpGs. We found no significant association between the previously implicated CpG and either AN or BN...

Developmental dyslexia (DD) is a neurobiological disorder featured by reading disabilities. In recent years, genome-wide approaches provided new perspectives to discover novel candidate genes of DD. In a previous study, rs9313548 located downstream of FGF18 showed borderline genome-wide significant association with DD. Herein, we selected rs9313548 and 11 independent tag single nucleotide polymorphisms covering gene region of FGF18 to perform association analysis with DD among 978 Chinese dyslexic cases and 998 controls recruited from elementary schools...

OBJECTIVE: Converging evidence has suggested ankyrin 3 (ANK3) as a risk gene for bipolar disorder (BD). However, association studies investigating its genetic variants and BD susceptibility have reported inconsistent results. In the present meta-analysis, we aimed to establish whether ANK3 single nucleotide polymorphisms (SNPs) confer increased risk for BD. METHODS: PubMed, Medline, PsycINFO, Embase, and Scopus were searched for literature published up to January 2017...

OBJECTIVE: The main aim of the current study was to investigate epigenetic alterations in serotonin 2A receptor (HTR2A) exon I CpG sites as possible risk factors for suicidal behavior. We also aimed to analyze the epigenetic alterations in two different tissues as epigenetic mechanisms are tissue specific. These epigenetic changes may lead to a better prediction of suicidal behavior. METHODS: Direct CpG methylation analysis was carried out on genomic DNA from the saliva of 20 schizophrenia suicide attempters and 27 non-attempters, and from post-mortem brain tissues of nine suicide victims and 11 controls...

The polymorphisms of the serotonin receptor 2C (HTR2C) gene have been proposed to influence suicidal behavior. The aim of our study was to explore the role of the HTR2C gene variant Cys23Ser (rs6318) in the pathogenesis of suicidal behavior through a systematic review and meta-analysis. The search was performed using EBSCO and PubMed databases. To be included in the analysis, the studies had to evaluate suicidal behavior (attempted, ideation, or completed suicide). The results of the meta-analysis were expressed as odds ratios (ORs)...

OBJECTIVE: We examined whether established metabolic risk genetic variants in the population confer a risk for increased waist circumference in patients with schizophrenia spectrum disorders and also an association with schizophrenia spectrum disorders irrespective of waist circumference. PATIENTS AND METHODS: We analyzed the association in (i) a case-case model in which patients with schizophrenia spectrum disorder with increased waist circumference (≥80 cm for women and ≥94 cm for men) (n=534) were compared with patients with normal waist circumference (<80 cm for women; <94 cm for men) (n=124), and in (ii) a case-control model in which schizophrenia spectrum disorder patients with increased waist circumference or irrespective of waist circumference were compared with population-derived controls (n=494) adjusted for age, sex, fasting glucose, smoking, and family history of diabetes...

AIM/OBJECTIVES/BACKGROUND: ZNF804A has been investigated widely as a candidate susceptibility gene for mental disorders in individuals of different ethnicities. However, in the Han Chinese population, most studies of this gene have focused on associations of the common single nucleotide polymorphism (SNP) rs1344706. METHODS: To investigate additional common variants within ZNF804A, we carried out a case-control study of 13 SNPs distributed across the whole gene, in 1330 schizophrenic patients, 1045 major depressive disorder patients, and 1235 normal controls...

Major depression disorder (MDD) is a complex neuropsychiatric disorder and an increasing number of genetic risk variants are being identified. Investigation of their influence in the general population requires accurate and efficient assessment of depressive symptoms. Here, clinical interviews conducted by clinicians are the gold standard. We investigated whether valid and reliable clinical phenotypes can be obtained efficiently using self-administered instruments. Lifetime depressive symptoms and lifetime MDD diagnosis were assessed in 464 population-based individuals using a clinical interview and a structured, self-administered checklist...

OBJECTIVES: Inbreeding increases the probability of homozygosity of deleterious alleles. Inbreeding and runs of homozygosity (ROH) are associated with an increased risk for disease phenotypes, including schizophrenia and other psychiatric disorders. The effects of inbreeding, ROH, homozygous deletions, and other copy number variations (CNVs) on risk for depression and suicide attempt (SA) were quantified in an Arab Bedouin Kindred. METHODS: We carried out genetic analyses of 439 individuals from an Arab kindred with high rates of depression and suicidal behavior...

AIM: Genetic and clinical complexities are common features of most psychiatric illnesses that pose a major obstacle in risk-gene identification. Attention deficit hyperactivity disorder (ADHD) is the most prevalent child-onset psychiatric illness, with high heritability. Over the past decade, numerous genetic studies utilizing various approaches, such as genome-wide association, candidate-gene association, and linkage analysis, have identified a multitude of candidate loci/genes. However, such studies have yielded diverse findings that are rarely reproduced, indicating that other genetic determinants have not been discovered yet...
