achondroplasia
Achondroplasia is a genetic disorder whose primary feature is dwarfism. It is the most common cause of dwarfism and affects about 1 in 27,500 people. In those with the condition, the arms and legs are short, while the torso is typically of normal length. Those affected have an average adult height of for males and for females. Other features can include an enlarged head with prominent forehead (frontal bossing) and underdevelopment of the midface (midface hypoplasia). Complications can include sleep apnea or recurrent ear infections. Achondroplasia includes the extremely rare short-limb skelet

cyclopia
Cyclopia (named after the Greek mythology characters cyclopes), also known as alobar holoprosencephaly, is the most extreme form of holoprosencephaly and is a congenital disorder (birth defect) characterized by the failure of the embryonic prosencephalon to properly divide the orbits of the eye into two cavities. Its incidence is 1 in 16,000 in born animals and 1 in 200 in miscarried fetuses.

sirenomelia

Sirenomelia, also called mermaid syndrome, is a rare congenital deformity in which the legs are fused together, giving the appearance of a mermaid's tail, hence the nickname.

Situs inversus
Situs inversus is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions. The normal arrangement of internal organs is known as situs solitus. Many people with situs inversus have no medical symptoms resulting from the condition, although cardiac problems are the most common complication. Until the advent of modern medicine, it was usually undiagnosed.

aniridia
Aniridia is a condition characterized by the absence or near absence of the iris, the colored, muscular ring in the eye that controls the size of the pupil and regulates the amount of light entering the eye. This absence results in a primarily black appearance of the central eye. Aniridia can be congenital, typically affecting both eyes, or caused by a penetrant injury. Congenital aniridia is not simply an iris defect but a more complex condition affecting multiple parts of the eye, with macular and optic nerve hypoplasia, cataract, and corneal changes. Vision may be severely compromised and t

agenesis
In medicine, agenesis () refers to the failure of an organ to develop during embryonic growth and development due to the absence of primordial tissue. Many forms of agenesis are referred to by individual names, depending on the organ affected:
clitoridectomy
Clitoridectomy or clitorectomy is the surgical removal, reduction, or partial removal of the clitoris. It is rarely used as a therapeutic medical procedure, such as when cancer has developed in or spread to the clitoris. Commonly, non-medical removal of the clitoris is performed during female genital mutilation.

diprosopus

Diprosopus (, "two-faced", from , , "two" and , [neuter], "face", "person"; with Latin ending), also known as craniofacial duplication (cranio- from Greek , "skull", the other parts Latin), is an extremely rare congenital disorder whereby parts (accessories) or all of the face are duplicated on the head.

polymelia
Polymelia is a birth defect in which an affected individual has more than the usual number of limbs. It is a type of dysmelia. In humans and most land-dwelling vertebrates, this means having five or more limbs. The extra limb is most commonly shrunken or deformed. The term is from Greek πολυ- "many", μέλεα "limbs".
heterotopia

Marinesco-Sjogren syndrome
Marinesco-Sjogren syndrome (MSS) belongs to the group of autosomal recessive cerebellar ataxias. Cardinal features of MSS are cerebellar ataxia, congenital cataract, and delayed psychomotor development.
porencephaly
Porencephaly is an extremely rare cephalic disorder involving encephalomalacia. It is a neurological disorder of the central nervous system characterized by cysts or cavities within the cerebral hemisphere. Porencephaly was termed by Heschl in 1859 to describe a cavity in the human brain. Derived from Greek roots, the word porencephaly means 'holes in the brain'. The cysts and cavities (cystic brain lesions) are more likely to be the result of destructive (encephaloclastic) cause, but can also be from abnormal development (malformative), direct damage, inflammation, or hemorrhage. The cysts an
