The DISC1 gene is one of the potential candidate gene involved in Schizophrenia risk. In the present study, we performed case-control association study using TaqMan based chemistry in which a total of 382 individuals, 152 Schizophrenia patients and 230 healthy controls were genotyped to explore the association of rs3738401 and rs16854954 of DISC1 gene with susceptibility to Schizophrenia risk in North Indian population of Jammu region. The findings from the study revealed that rs3738401 was significantly associated with Schizophrenia and the G allele of rs3738401 is associated with increased risk for the disorder (OR = 1.66; [1.22–2.24 at 95%CI] P = 0.001) whereas other variant rs16854954 of DISC1 gene was not found to be associated with the disease(OR = 0.96, [0.71–1.30 at 95% CI] P = 0.75). The present study offers an important evidence on the genetic cause of DISC1 gene in North Indian population and further strengthens the GWAS findings on the role of DISC1 in schizophrenia risk. This study provides the holistic view about the Schizophrenia in Jammu region, North Indian population and it can be a hallmark if verified on a very large sample size (cohort).</p></div>","PeriodicalId":38190,"journal":{"name":"Meta Gene","volume":"29 ","pages":"Article 100923"},"PeriodicalIF":0.7,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.mgene.2021.100923","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48181037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oligoasthenozoospermia (OA) is one of the most severe idiopathic MI forms, conditioned with decreased sperm motility and count. However, its pathology remains unclear, but few genetic factors have been identified. The main aim of this study was to find genetic variations in spermatogenic genes with severe OA. Semen and blood samples were collected from 250 MI subjects. Semen analysis, karyotyping, and Y microdeletion was performed to retain purely idiopathic MI cases (<em>n</em> = 247). 40 OA cases were identified, of which four severe cases were subjected to whole-exome sequencing, bioinformatics analyses, and pathway analysis, followed by validation of pathogenic variants in the remaining 36 OA cases through Sanger sequencing. We identified six variants in exon5 of gene <em>PSPH,</em> of which four variants were predicted to be pathogenic and two damaging mutations in exon4. In this study, we propose the novel role of <em>the PSPH</em> gene in their different mechanistic pathways. Detailed pathway analysis of enzyme PSPH involved in <span>l</span>-serine biosynthesis demonstrated that its dysfunction could cause a decrease in sperm count and sperm motility. The hypothesized function of PSPH in eliciting OA has been described.</p></div>","PeriodicalId":38190,"journal":{"name":"Meta Gene","volume":"29 ","pages":"Article 100897"},"PeriodicalIF":0.7,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.mgene.2021.100897","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"54836193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
