BMAL1
BMAL1 (basic helix-loop-helix ARNT like 1; HGNC-approved symbol, historically also called ARNTL) encodes a core transcription factor of the mammalian circadian clock that dimerizes with CLOCK to drive rhythmic, 24-hour expression of clock-controlled genes across the body. Because this circadian machinery helps time skin and metabolic responses to daylight, BMAL1 variants are examined here for their role in how vitamin D genetics interact with sun exposure and season.
