Her family reports that Lali eats with both mouths, and also blinks in time across all four of her eyes. Although this condition is classically considered conjoined twinning (which it resembles), this anomaly is not normally due to the fusion or incomplete separation of two embryos. It is the result of a protein called Sonic Hedgehog homolog (SHH). The SHH protein and its corresponding gene have been found to play an important role in signaling craniofacial patterning during embryonic development. Among other things, the SHH protein governs the width of facial features. In excess, it leads to widening of facial features and to duplication of facial structures. The greater the widening, the more of the structures are duplicated, often in a mirror image form. This has been demonstrated in the laboratory by introducing pellets of the SHH protein into chicken embryos, resulting in chickens with duplicate beaks. Insufficient amounts of that protein lead to opposite conditions such as cyclopia where facial features are insufficiently developed.

A baby, who was born with two faces, has surprisingly been diagnosed as having good health. The baby has attracted enormous attention in India and is being worshipped as the reincarnation of the Hindu goddess, Durga.
