α-Kinase 2 is a novel candidate gene for inherited hypertension in Dahl rats
Bibliographic record
Abstract
OBJECTIVES: The interval harboring a quantitative trait locus for blood pressure (BP), C18QTL3, contains β-2 adrenergic receptor (Adrb2) and neural precursor cell expressed, developmentally downregulated 4-like (Nedd4l) genes. None of the other genes in the C18QTL3-residing interval is known to affect BP. The identification of C18QTL3 might uncover a brand new gene that could prosper into a novel diagnostic and/or therapeutic target for essential hypertension, if neither Adrb2 nor Nedd4l could be upheld as candidate genes. METHODS: Congenic fine resolution was combined with gene analyses. RESULTS: The gene encoding α-kinase 2 (Alpk2) contains a three base-pair deletion and multiple nonconserved mutations in its coding region in Dahl salt-sensitive (DSS) rats. In contrast, the gastrin-releasing peptide gene (Grp) possesses two nonconserved mutations, designated as single nucleotide polymorphisms 1 and 2 (i.e. SNP1 and SNP2), but could not be supported as a candidate gene because the C18S.L14 congenic strain displayed a homozygous DSS genotype at both SNP1 and SNP2. Furthermore, Adrb2 and Nedd4l could not account for the BP-diminishing effect of Lewis alleles in C18S.L14, as their DSS alleles bear functionally identical domains as those of Lewis, and no evidence of differential expression and splicing was evident. No significant nucleotide variations were found in 13 other genes closely linked to Alpk2. CONCLUSION: Alpk2 emerged as a strong candidate gene for C18QTL3. The present study is the first to implicate Alpk2 in the genetics of polygenic hypertension and paves the way for novel gene discovery.

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.
