Incontinentia Pigmenti in an XY Boy: Case Report and Review of the Literature
Bibliographic record
Abstract
BACKGROUND: Incontinentia pigmenti (IP) is a rare genetic skin disorder with X-linked dominant inheritance and a characteristic sequence of cutaneous manifestations, which is regarded as lethal in XY males. OBJECTIVE: To report a case of a surviving XY male with the common IKBKG (NEMO) gene deletion confirming IP. METHODS AND RESULTS: A newborn XY male with suspected IP underwent a skin biopsy on affected tissue for histopathology. Molecular genetic testing was also performed on the specimen and revealed the common IKBKG gene deletion with a pattern suggestive of somatic mosaicism. Our findings are aligned with a PubMed literature review for XY males with IP and documented IKBKG mutation. We determined that only 10 such genetically proven cases have been reported, including our case. CONCLUSION: Although relatively rare, cases of IP in XY males with the common NEMO mutation have likely been underreported due to the unavailability of appropriate testing in the past. Karyotype and molecular testing should be considered when clinical suspicion of IP arises for a male patient.

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.
