An Iris that is split in half with two colors

A rare genetic condition called “sectoral heterochromia” causes the iris of the eye to appear in two different colors. Most cases are hereditary and with a person from birth, but in very rare cases they can be caused by diseases or genetic mutations. Though multiple causes have been posited, the scientific consensus is that a lack of genetic diversity is the primary reason behind heterochromia. This is due to a mutation of the genes that determine melanin distribution at the 8-HTP pathway, which usually only become corrupted due to chromosomal homogeneity. This condition also occasionally appears in animals.

Mirror Hands

Ulnar dimelia, also referred to simply as Mirror hand, is a very rare congenital disorder characterized by an absence of radial ray, duplication of the ulna, duplication of carpals, metacarpals, phalanges and symmetric polydactyly. In some cases, surgical amputation is performed to remove the duplicate carpals, metacarpals, and phalanges.

Missing Fingers

Amniotic Band Syndrome is considered an accidental event, and it does not appear to be genetic or hereditary. A strong relationship between ABS and clubfoot (also called “talipes”) exists. A 31.5% of associated clubfoot deformity and ABS can be correlated with 20% occurring bilaterally. Other abnormalities found with ABS include: clubhands, cleft lip, and/or cleft palate, and hemangioma

A scar in the eye

A macular pucker is scar tissue that has formed on the eye’s macula, located in the center of the light-sensitive tissue called the retina. The macula provides the sharp, central vision we need for reading, driving, and seeing fine detail. A macular pucker can cause blurred and distorted central vision.
