Popis: Introduction Depression is a chronic, recurrent mental disorder with a moderate level of genetic impact. Modern GWAS of depression require extra-large sample sizes and new effective, clinically sensitive, objective and simple to fill online phenotyping tools for population studies are necessary today. Objectives Aim: to test online phenotyping tools based on clinical and psychometric instruments to evaluate depressive symptoms in population cohort for using in GWAS Methods Participants: 2610 Russian-speaking respondents- clients of Genotek Ltd., provider of genetic testing services in Russian Federation. The online survey included HADS-D (Hospital Anxiety and Depression Scale - depression subscale), original questionnaire adapted for self-report from major depression DSM-5 criteria, questions about sex and age. Three research phenotypes were defined: quantitative “HADS-D score” and two categorical “HADS-D depression” (cut-off 8 points) - 20.63 %, “DSM depression” 16.73 %. DNA samples obtained from saliva were genotyped on Illumina Infinium GSA v1.0/v2.0/v3.0 microarrays. GWAS analysis was performed independently for each of the research phenotypes. Results None of the signals reached genome-wide significance (p value 10-8), but some signals with subthreshold significance were identified including four signals in the genes encoding proteins: “DSM_Depression”: rs2131596 in GRIP1 (p=3.682e-06,β=0.6965), rs11158021 in SAMD4A (p=2.841e-06, β=0.6762), “HADS-D Depression”: rs2425793 in CDH22 (p=4.408e-07, β=1.539), rs36006890 in PDIA6 (p = 6.529e-07, β=1.549). Conclusions Preliminary results of the first GWAS of depression symptoms in the Russian population are acceptable and confirm the accuracy of the research strategy using online phenotyping tools based on clinical and psychometric instruments and provide basis for further studies. Disclosure The study was supported by Russian Science Foundation Grant # 20-15-00132
