Meckel syndrome is a rare inherited disorder characterized by abnormalities affecting several organ systems of the body. Three classic symptoms are normally associated with Meckel syndrome: protrusion of a portion of the brain and its surrounding membranes (meninges) through a defect in the back of the skull (occipital encephalocele), multiple cysts on the kidneys (cystic kidneys), and extra fingers and/or toes (polydactyly). Affected children or fetuses may also have abnormalities affecting the head and face (craniofacial area), liver, lungs, heart, and genitourinary tract. Meckel syndrome is inherited as an autosomal recessive condition through thirteen genes: B9D1, B9D2, CC2D2A, CEP290, MKS1, RPGRIP1L, TCTN2, TCTN3, TMEM67, TMEM107, TMEM216, TMEM231 and TMEM237.
Most fetuses affected with Meckel syndrome die before birth due to a lack of amniotic fluid surrounding the fetus (oligohydramnios) or incomplete development of the lungs (pulmonary hypoplasia). Because of these serious health problems, infants that are born do not survive longer than a few days or weeks. Most affected infants die of kidney failure or respiratory problems.Introduction
The first report of Meckel syndrome was published by Johann Friedrich Meckel in 1822. In 1934, G.B. Gruber published reports on individuals with Meckel syndrome and named the disorder dysencephalia splanchnocystica.
