Basophobia: A case report highlighting potential genetic vulnerability.

Basophobia, or space phobia, represents a rare form of specific phobia characterized by excessive fear of falling in open spaces without visible support. While familial aggregation has been documented in specific phobia generally, there are no previous reports documenting family clustering in basophobia specifically. We report the case of a 57-year-old woman who developed basophobia following a minor fall, with the notable finding of similar complaints in 30-year-old son. This case represents the first documented familial aggregation of basophobia and raises important questions about genetic vulnerability factors in this specific phobic subtype.
