Introduction
The sinoatrial node (SAN) is the primary pacemaker of the heart that initially develops from part of pro-pacemaking embryonic venous pole that expresses both Hcn4 and the transcriptional factor Shox2.[1]

Molecular
Hcn4
Hyperpolarization-Activated Cyclic Nucleotide-Gated Potassium Channel 4 (HCN4) gene located at 15q24.1, the 1,203 amino acid protein contains 6 putative transmembrane segments, a pore region, and a cyclic nucleotide-binding domain.

Shox2
Short Stature Homeobox 2 (SHOX2) gene located at 3q25.32, the protein acts as a homeobox transcription factor.
- mouse og12 gene - developmental sinus venosus (aorta), female genitalia, diencephalon, mes- and myelencephalon, nasal capsula, palate, eyelid, and limbs
