Disease family
This is a subtype of depressive disorder. Genetic, therapeutic, and trial evidence is largely curated at the broader-term level — see the parent page for the associated-gene cohort and molecular evidence.
Classification path: disease › human disease › disease by developmental or physiological process › psychiatric disorder › mental disorder › mood disorder › depressive disorder › seasonal affective disorder

Genetics & variants
GWAS landscape
No GWAS associations recorded — common-variant (GWAS) studies don’t cover this disease (typical for Mendelian / rare diseases). See the curated gene cohort and Mendelian overlap below.
Variant details and genetic-evidence tiers
No tiered GWAS variants or ClinVar records for this disease.
Genes & proteins
No associated-gene cohort resolved for this disease. Atlas builds the molecular and therapeutic sections — associated genes, protein families, druggability, pathways, interactions, and drug associations — by aggregating over a disease’s associated genes (resolved via GWAS / GenCC / ClinVar / CIViC), and none resolved here. This is expected for antibody-mediated, autoimmune, or otherwise non-gene-defined conditions; the curated evidence for this disease is its clinical features, GWAS susceptibility, and clinical trials (above).
Function
No pathway enrichment — requires an associated-gene cohort.
Therapeutics
No druggable-target or therapeutic data for this disease’s cohort.
