Candidate genes on chromosome 6p in obsessive-compulsive disorder and schizophrenia.
Gwyneth Ching Mung Zai
Written in English
Obsessive-compulsive disorder (OCD) and schizophrenia (SCZ) are serious neuropsychiatric disorders that might involve autoimmune processes. Two genes, mapping to a risk region for OCD/SCZ, the myelin oligodendrocyte glycoprotein (MOG), which mediates the complement cascade, and the gamma-aminobutyric acid type B receptor 1 (GABBR1), which functions in the major inhibitory neurotransmitter system, represent candidates for OCD/SCZ. We investigated the transmission of alleles/haplotypes of four MOG and five GABBR1 polymorphisms for possible association with 191 SCZ case-control pairs, 160 OCD and 111 SCZ families using the transmission disequilibrium test, family-based association test or Kruskal-Wallis Test. Significant associations were observed for MOG-(TAAA)n (P = 0.022) with OCD and with OCD severity level ( P = 0.020). The MOG haplotype-184.108.40.206 (P = 0.011) was associated with OCD. Trends of overtransmission of GABBR1-7265A variant (P = 0.071) and haplotype-220.127.116.11.1 (P = 0.065) were observed in OCD. Although our results suggest that MOG/GABBR1 were not associated with SCZ, both genes might play a role in OCD.

A new research study, which focused on OCD causes, has discovered a link between obsessive-compulsive behavior and a neural dysfunction in a certain region of the brain. Obsessive compulsive disorder can be an extreme emotional challenge as it often manifests itself in anxiety, worries, fears, tics, and unnecessary repetitive behavior. In some instances, the condition. Obsessive–compulsive disorder (OCD) is a chronic disorder occurring in approximately 2% of the population. Between 40 and 60% of patients are nonresponders to .
The cause of obsessive-compulsive disorder is concerned with identifying the biological risk factors involved in the expression of obsessive-compulsive disorder (OCD) symptomology. The leading hypotheses propose the involvement of the orbitofrontal cortex, basal ganglia, and/or the limbic system, with discoveries being made in the fields of neuroanatomy, neurochemistry, neuroimmunology. With their candidate genes in hand, the team examined people with OCD and compared them to people without the condition. This helped them to cull the list down to just four genes expressed in the brain – called NRXN1, HTR2A, CTTNBP2, and REEP3 – which, when they undergo mutations, are significantly associated with human OCD.
Cambridge researchers have discovered that individuals with obsessive compulsive disorder (OCD) and their close family members have distinctive patterns .

A study from the Obsessive-Compulsive Disorder Collaborative investigated this question in families with OCD; 32% of the subjects had trichotillomania or another grooming disorder. Several SNPs within the SAPAP3 gene were significantly associated with a grooming disorder, using a family-based association by: 9.
Obsessive-compulsive disorder (OCD [MIM ]) is a severe psychiatric illness that is characterized by intrusive and senseless thoughts and impulses (obsessions) and by repetitive behaviors (compulsions).OCD is estimated to affect 1%–3% of the population, and the World Health Organization ranks OCD as 1 of the 10 most disabling medical conditions worldwide (Murray and Lopez ).Cited by: Obsessive-compulsive disorder (OCD), a severe mental disease manifested in time-consuming repetition of behaviors, affects 1 to 3% of the human population.
While highly heritable, complex genetics has hampered attempts to elucidate OCD etiology. Dogs suffer from naturally occurring compulsive disorders that closely model human OCD, manifested as an excessive repetition of normal Cited by: There are found genes that have been identified to be associated with obsessive compulsive disorder (OCD).
These genes have been found to alter the circuitry of the brain in a. Obsessive-compulsive disorder (OCD) is characterized by recurring obsessions and/or compulsions and has been estimated to affect nearly 5 million people in the United States (Karno et al., ).Evidence for a strong genetic component in OCD comes from twin studies, family genetics studies, and segregation analyses, as reviewed by Alsobrook et al.

Grados, Rebecca Dang. Obsessive-compulsive disorder (OCD) (Mendelian Inheritance in Man ) is a common neuropsychiatric disorder consisting of repeated, distressing ego dystonic thoughts (obsessions) and behaviors (compulsions) with a worldwide prevalence of 1% to 3% (1, 2, 3, 4).Family, segregation, and twin studies clearly demonstrate that OCD is familial, with estimated heritabilities for obsessive Cited by: Obsessive-compulsive disorder (OCD) is a neuropsychiatric disease and a complex genetic illness.

Introduction. Obsessive–compulsive disorder (OCD) is a common and severe psychiatric disorder associated with high levels of morbidity and disability (Murray and Lopez,Bobes et al., ).Based on population surveys, the lifetime prevalence of OCD in adults is estimated at around 1–4% (Angst et al.,Kessler et al., ).

Epidemiological data are similar in children and adults, i.e., between 1 and 3% of the general population suffer from OCD. Children with OCD are often seriously impaired in their development.

Mutant Gene Linked to Obsessive Compulsive Disorder. Analysis of DNA samples from patients with obsessive compulsive disorder and related illnesses suggests that these neuropsychiatric disorders affecting mood and behavior are associated with an uncommon mutant, malfunctioning gene that leads to faulty transporter function and regulation.
Four genes have been identified that are linked to obsessive compulsive disorder (OCD). The genes all play a role in the same brain circuit, and may. Scientists looking for genetic factors behind obsessive compulsive disorder looked for clues in the DNA of humans and two animal species.
Genes active in a particular brain circuit emerged. Importance Despite a remarkable co-occurrence of obsessive-compulsive disorder (OCD) and schizophrenia, little is known about the clinical and etiological relationship of these 2 disorders.
Exploring the degree to which these disorders share etiological factors might provide useful implications for clinicians, researchers, and those with the by:
