intelligence gene intelligence gene A gene on chromosome 12q15 that encodes high-mobility group (non-histone chromosomal) protein isoform I-C, a variant of which was identified by Project ENIGMA (a massive multi-centre, multination survey study) as a marker for slightly higher scores in IQ tests and slightly bigger brains. Those with the so-called intelligence gene had a cytosine instead of a thymine on a particular locus of HMGA2. Another candidate intelligence gene—STX1A—was identified in patients with Williams syndrome. |
