Which Superform, when combined with Piebald, is noted for highest eye risk?

Super Lesser

While combining Piebald with several Superforms from the BEL complex is known to create a risk for microphthalmia, community insights suggest the expression of the small eye phenotype is often most severe and consistent when the Piebald gene is paired with the Super forms of the Lesser/Butter spectrum. Super Lesser is explicitly listed as one of the specific Superforms that, when combined with Piebald, results in a high consistency of eye defects. This highlights that not all BEL Superforms carry the exact same severity risk profile when interacting with the Piebald gene.
