Molecular and immunological basis of X‐linked lymphoproliferative disease
Bibliographic record
Abstract
X-linked lymphoproliferative (XLP) disease is a human immune dysfunction characterized primarily by an inappropriate response to Epstein-Barr virus infection. In 1998, it was discovered that XLP is caused by inactivating mutations in the SAP/SH2D1A/DSHP gene. This gene codes for an immune cell-specific polypeptide termed SAP (SLAM-associated protein) that is composed almost exclusively of an Src homology 2 (SH2) domain. By way of its SH2 domain, SAP interacts with tyrosine-based motifs located in the cytoplasmic region of members of the SLAM (signaling lymphocyte activation molecule) family of receptors. Recent findings indicate that SAP is required for the function of SLAM-related receptors, as a consequence of its capacity to promote the recruitment and activation of the Src-related protein tyrosine kinase FynT, thereby allowing SLAM receptor-mediated protein tyrosine phosphorylation signals in immune cells. Functional and genetic analyses suggest that the phenotype associated with XLP is caused in large part by defects in the functions of SLAM-related receptors due to SAP deficiency.

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.
