A novel compound heterozygous variant in CYP19A1 resulting in aromatase deficiency with normal ovarian tissue.
2020
BACKGROUND Aromatase deficiency leading to virilization in mother and female fetuses during pregnancy is a rare disease. It is characterized by impaired estrogen production, increased gonadotropins, and ovarian cysts. CASE Herein, we report a clinical phenotype of the virilized female due to a novel compound heterozygous variant in CYP19A1 [IVS10 + 1 G > A; c.344 G > A (p.R115Q)], with normal gonadotropin levels at the time of admission and histologically normal ovarian tissues. CONCLUSION Aromatase deficiency should also be considered even if the initial follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels are normal, and ovarian cysts are lacking.
