Chromosomal Mapping of HCaRG, a Novel Hypertension-Related, Calcium-Regulated Gene
Bibliographic record
Abstract
We recently identified a novel gene that is negatively regulated by extracellular calcium concentration with higher levels of transcripts in hypertensive animals (SHR). We named this gene HCaRG (Hypertension-related, Calcium-Regulated Gene). In this work we report the chromosomal localization of the HCaRG gene among different species. We identified a BglII RFLP between BN.lx and SHR rats. We then analysed the strain distribution pattern of this RFLP in 31 RIS, originating from BN.lx and SHR rats, and compared it to the segregation of 475 markers localized in the rat genetic map. Hcarg localizes to the rat chromosome 7 between the markers Mit3 and Mit4. This region is homologous to human chromosome 8q21-24. We identified three clones in Genbank that contain the sequence of HCaRG. It was therefore possible to narrow down the localization of human HCaRG to chromosome 8q24.3. Furthermore, a suggestive localization of mouse Hcarg based on conservation of linkage between human and mouse is on chromosome 15. We previously identified a putative calcium-binding motif (EF-Hand) and a nuclear receptor-binding domain (LxxLL) in the rat sequence of the HCaRG protein. Sequence comparison between five different species showed that these domains are highly conserved. Furthermore, a search of ESTs in Genbank for homologous sequences showed that HCaRG is expressed only in eukaryotes, particularly in mammals.

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.
