Anodontia, also known as anodontia vera in dentistry, is a very rare genetic disorder. This disease is characterized by congenital absence of all permanent and primary teeth. Anodontia is associated with a group of nerve and skin syndromes known as ?ectodermal dysplasias?. Anodontia is commonly part of different syndromes, which rarely occur as an isolated disorder. Partial anodontia, wherein the patient suffers from congenital absence of two or more teeth, could also occur. This is also known as ?oligodontia? and ?hypodontia?. Some patients may also suffer from congenital absence of all third molars and all wisdrom teeth. [read more]

Juvenile idiopathic arthritis (JIA) previously identified as juvenile rheumatoid arthritis (JRA) is the most ordinary type of unrelenting arthritis in children. Occasionally it is called as juvenile chronic arthritis (JCA) a term that is not exact as JIA does not include all types of persistent childhood arthritis. Arthritis causes the lining of the joint (synovium) to swell. JIA is a division of arthritis noticeable during childhood, which might be temporary and self-limited or persistent. It varies considerably from arthritis usually noticed in adults (osteoarthritis, rheumatoid arthritis), and other kinds of arthritis that can present in infancy which are persistent conditions.

Bilateral renal agenesis is uncommon and is a serious condition, related to Potter's Syndrome. Bilateral renal agenesis is the lack of both kidneys at birth. It is a genetic disorder characterized by a failure of the kidneys to develop as a fetus inside the womb. This absence of kidneys results to a deficiency of amniotic fluid (or oligohydramnios) in a pregnant woman. Normally, the amniotic fluid serves as a cushion for the developing fetus. When there is not enough amount of this fluid, compression of the fetus may occur resulting in further malformations of the baby. It is the consequence of failure of differentiation of the metanephric blastema during the 25?28th day of development and both ureters and kidneys and renal arteries are missing. This disorder is more commonly found in infants born of a parent who has a kidney malformation, particularly the absence of one kidney (or unilateral renal agenesis). Studies have proven that unilateral renal agenesis and bilateral renal agenesis are genetically related to eachother. 1 out of 3 infants with this congenital defect are not born alive. Most infants that are born alive do not live beyond the coarse of four hours. [read more]
Caudal regression syndrome is an uncommon disorder wherein the fetal spine's bottom portion does not properly develop. As a result, abnormalities that can be mild or severe occur. The syndrome can lead to various problems, varying from partial nonappearance of the spine's tailbone areas, to severe cases entailing significant malformation of pelvis, lower vertebrate, and spine.

Gliomas most commonly occur in the brain but can also occur in any other part of the central nervous system. Gliomas can also be classified as the following: oligodendroglioma, ependymoma, astrocystoma, and mixed gliomas. [read more]

Renal agenesis is an inborn condition in which an infant is born without one or both kidneys. The absence of one kidney at birth is called unilateral renal agenesis; while the absence of both kidneys is called bilateral renal agenesis. [read more]

This disorder is an extremely rare chromosomal disorder. Affected individuals have 3 chromosomes for a total of sixty-nine rather than the normal 46 chromosomes. Unborn children with Triploid syndrome are usually lost through early miscarriage but those who make it survive for as long as five months. [read more]
This disorder is a rare lethal chromosome abnormality caused by the presence of an entire extra set of chromosomes. Unborn children with triploidy has 69 chromosomes rather than 46. Most fetuses are miscarried during pregnancy and those that survive usually have severe growth retardation and multiple birth defects. [read more]
