Abstract
FOXL2 is a putative transcription factor involved in ovarian development and function. Its mutations in humans are responsible for the blepharophimosis syndrome, characterized by eyelid malformations and premature ovarian failure (POF). Here we have performed a comparative sequence analysis of FOXL2 sequences of ten vertebrate species. We demonstrate that the entire open reading frame (ORF) is under purifying selection leading to strong protein conservation. We also review recent data on FOXL2 transcript and protein expression. FOXL2 has been shown 1) to be the earliest known sex dimorphic marker of ovarian determination/differentiation in vertebrates, 2) to have, at least in mammals, an ovarian expression persisting until adulthood. The conservation of its sequence and pattern of expression suggests that FOXL2 might be a key factor in the early development of the vertebrate female gonad and involved later in adult ovarian function. Finally, we provide arguments for the existence of an alternative transcript in rodents, that may arise from a differential polyadenylation. Although it has only been demonstrated in rodents, its presence/absence in other species deserves further investigation.

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 it
