Recessive gene surfaces after sibling marriage
Siblings Desdemona and Lefty Stephanides flee the 1922 burning of Smyrna, pass as strangers on the ship to America, and marry, while their son later marries his cousin. Each carries a hidden recessive mutation for 5-alpha-reductase deficiency, and it surfaces in their grandchild Calliope, raised as a girl in suburban Detroit, who begins to virilize at puberty. Calliope is identified as intersex after a concussion at fourteen, flees a surgeon's plan to 'normalize' her, and lives afterward as Cal.
