    Abstract Nicotine withdrawal symptoms contribute to relapse in smokers, thereby prolonging the harm caused by smoking. To investigate the molecular basis for this phenomenon, we conducted a genome-wide association study of DSM-IV nicotine withdrawal in a sample of African American (AA) and European American (EA) smokers. A combined AA and EA meta-analysis (n=8021) identified three highly correlated single nucleotide polymorphisms (SNPs) in the protocadherin (PCDH)-α, -β and -γ gene cluster on chromosome 5 that were associated with nicotine withdrawal (P<5 × 10

    Abstract Traditional genetic approaches have led to the identification of defects underlying an impressive array of diseases. Genetic terminology, Mendel's laws, chromosomes and linkage, statistical methods for linkage analysis, genetic markers, multilocus mapping, strategies in linkage studies, linkage heterogeneity, and the future of linkage analysis are discussed in this article. The molecular basis for most disorders, however, cannot be gleaned because there is no identifiable primary metabolic disorder.

    Abstract Unbiased genome-wide approaches can provide novel insights into the biological pathways that are important for human behavior and psychiatric disorder risk. The association of α-endomannosidase gene (MANEA) variants and cocaine-induced paranoia (CIP) was initially described in a study that used a whole-genome approach. Behavioral effects have been reported for other mannosidase genes, but MANEA function in humans and the clinical potential of the previous findings remain unclear. We hypothesized that MANEA would be associated with psychiatric phenotypes unrelated to cocaine use. We used a multi-stage association study approach starting with four psychiatric disorders to show an association between a MANEA single-nucleotide polymorphism (SNP; rs1133503) and anxiety disorders. In the first study of 2073 European American (EA) and 2459 African American subjects mostly with comorbid drug or alcohol dependence, we observed an association in EAs of rs1133503 with panic disorder (PD) (191 PD cases, odds ratio (OR)=1.7 (95% confidence interval (CI): 1.22-2.41), P=0.002). We replicated this finding in an independent sample of 142 PD cases (OR =1.53 (95% CI: 1.00-2.31), P=0.043) and extended it in an independent sample of 131 generalized social anxiety disorder cases (OR=2.15 (95% CI: 1.27-3.64), P=0.004). MANEA alleles and genotypes were also associated with gene expression differences in whole blood cells. Using publically available data, we observed a consistent effect on expression in brain tissue. We conclude that pathways involving α-endomannosidase warrant further investigation in relation to anxiety disorders.

    Abstract Opioids are very effective analgesics, but they are also highly addictive. Methadone is used to treat opioid dependence (OD), acting as a selective agonist at the μ-opioid receptor encoded by the gene OPRM1. Determining the optimal methadone maintenance dose is time consuming; currently, no biomarkers are available to guide treatment. In methadone-treated OD subjects drawn from a case and control sample, we conducted a genome-wide association study of usual daily methadone dose. In African-American (AA) OD subjects (n=383), we identified a genome-wide significant association between therapeutic methadone dose (mean=68.0 mg, s.d.=30.1 mg) and rs73568641 (P=2.8 × 10

    Abstract Suicide behavior in Huntington disease (HD) was assessed by examining the proportion of deaths attributed to suicide among 452 deceased individuals with HD and the number and pattern of attempted suicides among a total population of 831 HD patients from the National Huntington Disease Research Roster. It was found that 5.7% of deaths among affected persons resulted from suicide and 27.6% of patients attempted suicide at least once. Comparison of this group with the general population indicated that the proportion of deaths due to suicide among persons with HD is almost four times greater than the corresponding proportion for the U.S. Caucasian population. Age at onset of HD was not significantly different between HD suicide and non-suicide patients, although suicide occurred more frequently in the early to middle stages of the illness. The "success" rate among HD suicide attempters did not differ from the general population rates in several western European countries. The relatively high suicide and attempted suicide rates in HD indicate that thorough psychological testing of at-risk persons and extensive patient support systems must be integral components of a program to identify HD gene carriers using a genetic marker.

    Abstract There have been conflicting reports that individuals with Huntington disease (HD) are prone to abnormalities of carbohydrate metabolism. In this study information about the incidence and control of diabetes mellitus in 620 probands (278 living, 332 deceased) with HD and in their first and second degree relatives was obtained by questionnaire method from participants of the National HD Research Roster. Among the probands, 65 individuals (10.5%) were identified by the informant or verified by examination of Roster family records as diabetic. The prevalence of diabetes, particularly among those les than 50 years of age, is significantly greater than corresponding figures among the general U.S. Caucasian population (Scott 1977, Krolewski & Warram 1985). Incidence rates were not calculated because of ascertainment and other biases in the data. Results from the analysis of family data indicate that HD affected relatives of an HD proband with diabetes are 7 times as likely to have diabetes over the proband's non-HD relatives. A non-diabetic HD proband is equally likely to have an HD or non-HD relative with diabetes.

    Abstract Objective: Alzheimer's disease (AD) is a neurodegenerative disorder for which more than 20 genetic loci have been implicated to date. However, studies demonstrate not all genetic factors have been identified. Therefore, in this study we seek to identify additional rare variants and novel genes potentially contributing to AD.
    Methods: Whole exome sequencing was performed on 23 multi-generational families with an average of eight affected subjects. Exome sequencing was filtered for rare, nonsynonymous and loss-of-function variants. Alterations predicted to have a functional consequence and located within either a previously reported AD gene, a linkage peak (LOD>2), or clustering in the same gene across multiple families, were prioritized.
    Results: Rare variants were found in known AD risk genes including
    Conclusion: Utilizing large families with a heavy burden of disease allowed for the identification of rare variants co-segregating with disease. Variants were identified in both known AD risk genes and in novel genes.
