Gonadal Function, First Cases of Pregnancy, and Child Delivery in a Woman with Lipoid Congenital Adrenal Hyperplasia
Bibliographic record
Abstract
CONTEXT: Mutations in the steroidogenic acute regulatory protein (StAR) gene often cause lipoid congenital adrenal hyperplasia (LCAH). In this disorder an impairment of steroid synthesis leads to adrenal and gonadal insufficiencies with a particular female genital phenotype in both human karyotypes. Pregnancy in LCAH has not been yet reported. OBJECTIVE: We describe the first cases of pregnancy in a LCAH female patient bearing the L275P mutation in the StAR gene. DESIGN: We studied the gonadal function, pubertal development, and apply the appropriate hormonal therapy to support pregnancies. PATIENT: A 46,xx patient of French Canadian descent was diagnosed with LCAH at the age of 4.5 months. Substitution therapy with glucocorticoids and mineralocorticoids led to normal growth and development. Progressive pubertal development started at the age of 11 7/12 yr. Menarche occurred at 14 2/12 yr with normal regular menstruations thereafter but without ovulation. RESULTS: Clomiphene stimulation induced the first pregnancy at 25 4/12 yr of age. Spontaneous abortion occurred after 6 wk gestation. The second pregnancy (with clomiphene stimulation) was induced at the age of 26 yr. Progesterone (Prog) therapy was added at the 17th day of the cycle to protect pregnancy. Vaginal delivery of dichorionic-diamniotic twin pregnancy occurred at 30 wk gestation (two normal weight male babies). Two years later, again under clomiphene stimulation, she underwent another successful singleton pregnancy and delivered a normal weight female baby at 36 wk. The pregnancies were almost uncomplicated. CONCLUSION: Despite the dysfunctional StAR, pregnancy is possible under the proper therapeutic strategy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
