Genome-wide association studies (GWASs) in European populations have identified more than 100 schizophrenia-associated loci. A schizophrenia GWAS in a unique Indian population offers novel findings. To discover and functionally evaluate genetic loci for schizophrenia in a GWAS of a unique Indian population. This GWAS included a sample of affected individuals, family members, and unrelated cases and controls. Three thousand ninety-two individuals were recruited and diagnostically ascertained via medical records, hospitals, clinics, and clinical networks in Chennai and surrounding regions. Affected participants fulfilled DSM-IV diagnostic criteria for schizophrenia. Unrelated control participants had no personal or family history of psychotic disorder. Recruitment, genotyping, and analysis o

Genome-wide association studies of metabolites in Finnish men identify disease-relevant loci - Unknown journal (n.d.) · Unknown authors · PubMed 35347128
ABSTRACT: Few studies have explored the impact of rare variants (minor allele frequency < 1%) on highly heritable plasma metabolites identified in metabolomic screens. The Finnish population provides an ideal opportunity for such explorations, given the multiple bottlenecks and expansions that have shaped its history, and the enrichment for many otherwise rare alleles that has resulted. Here, we report genetic associations for 1391 plasma metabolites in 6136 men from the late-settlement region of Finland. We identify 303 novel association signals, more than one third at variants rare or enriched in Finns. Many of these signals identify genes not previously implicated in metabolite genome-wide association studies and suggest mechanisms for diseases and disease-related traits. The Finnis

Lifestyle context
Concrete actions anchored to the cited research. We do not prescribe, we describe.
Diet
-
niacin-rich foods for optimal metabolism Moderate
rs10866912 A-allele reduces NAPRT1 expression, impairing niacin metabolism; adequate intake supports brain function.
Include poultry, fish, mushrooms, peanuts, and whole grains; target 14-16mg daily
Discuss with your doctor
-
niacin status in context of schizophrenia susceptibility Moderate
NAPRT1 dysfunction from rs10866912-A reduces niacin availability in brain; niacin deficiency causes psychiatric symptoms; study suggests genotype and niacin status have treatment implications.
Ask doctor about assessing niacin status via blood test and discussing supplementation strategies
Supplements
-
niacin supplementation Moderate
Risk allele-associated NAPRT1 downregulation may impair endogenous niacin metabolism and utilization.
Discuss with doctor about testing niacin status and appropriate supplementation dosage
