What gene affects eye color? Hect domain and RCC1-like domain-containing protein 2 (HERC2) and OCA2. Finally, two major genes are responsible for eye color: HERC2 and OCA2. During the first studies to classify genes for eye color, OCA2 was believed to be the dominating factor for eye color determination.
