Gonadotropin-dependent Sexual Precocity in a Boy Affected by Pseudohypoparathyroidism
Bibliographic record
Abstract
Pseudohypoparathyroidism (PHP) is characterized by hypocalcemia and hyperphosphatemia due to PTH resistance. PHP type Ia is due to diminished G(s)alpha activity in several tissues, causing resistance to hormones whose action is mediated by cAMP. Only two cases of males with PTH type Ia who paradoxically showed sexual precocity have been described in the literature. We describe an 11.5 year-old boy affected by PHP without AHO but with associated true precocious puberty, who came to the I.C.U. for tetanic seizures and drowsiness due to severe hypocalcemia. Hyperphosphatemia, increased PTH levels and normal 25-OH-vitamin D values were present. Skeletal X-ray showed mild osteopenia. Brain MRI revealed symmetric calcifications in basal ganglia and in frontal areas. Thyroid and thyreotropinic function were normal. Testosterone levels were in the adult range, as well as basal and stimulated gonadotropin levels. Tanner stage P4, G4; testicular volume 12-15 mi. Molecular cytogenetics studies are now underway to further elucidate the etiology of this form of PHP.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
