Summaries for Anencephaly

NINDS : 53 Anencephaly is a defect in the closure of the neural tube during fetal development. The neural tube is a narrow channel that folds and closes between the 3rd and 4th weeks of pregnancy to form the brain and spinal cord of the embryo. Anencephaly occurs when the "cephalic" or head end of the neural tube fails to close, resulting in the absence of a major portion of the brain, skull, and scalp. Infants with this disorder are born without a forebrain (the front part of the brain) and a cerebrum (the thinking and coordinating part of the brain). The remaining brain tissue is often exposed--not covered by bone or skin. A baby born with anencephaly is usually blind, deaf, unconscious, and unable to feel pain. Although some individuals with anencephaly may be born with a rudimentary brain stem, the lack of a functioning cerebrum permanently rules out the possibility of ever gaining consciousness. Reflex actions such as breathing and responses to sound or touch may occur. The cause of anencephaly is unknown. Although it is thought that a mother's diet and vitamin intake may play a role, scientists believe that many other factors are also involved. Recent studies have shown that the addition of folic acid (vitamin B9) to the diet of women of childbearing age may significantly reduce the incidence of neural tube defects. Therefore it is recommended that all women of childbearing age consume 0.4 mg of folic acid daily.

MalaCards based summary : Anencephaly, also known as anencephalus, is related to isolated anencephaly and craniorachischisis. An important gene associated with Anencephaly is TRIM36 (Tripartite Motif Containing 36), and among its related pathways/superpathways are Metabolism of water-soluble vitamins and cofactors and One carbon pool by folate. The drugs Erenumab and Salmon calcitonin have been mentioned in the context of this disorder. Affiliated tissues include Neural Tube, brain and spinal cord, and related phenotypes are primary adrenal insufficiency and anencephaly

Disease Ontology : 12 A congenital nervous system abnormality characterized by failure of the anterior neuropore to close resulting in partial or complete absence of the cranial vault accompanied by absence of overlying tissues, including the brain and cerebral hemispheres, skull and scalp.

Genetics Home Reference : 25 Anencephaly is a condition that prevents the normal development of the brain and the bones of the skull. This condition results when a structure called the neural tube fails to close during the first few weeks of embryonic development. The neural tube is a layer of cells that ultimately develops into the brain and spinal cord. Because anencephaly is caused by abnormalities of the neural tube, it is classified as a neural tube defect. Because the neural tube fails to close properly, the developing brain and spinal cord are exposed to the amniotic fluid that surrounds the fetus in the womb. This exposure causes the nervous system tissue to break down (degenerate). As a result, people with anencephaly are missing large parts of the brain called the cerebrum and cerebellum. These brain regions are necessary for thinking, hearing, vision, emotion, and coordinating movement. The bones of the skull are also missing or incompletely formed. Because these nervous system abnormalities are so severe, almost all babies with anencephaly die before birth or within a few hours or days after birth.

NIH Rare Diseases : 52 Anencephaly is a type of neural tube defect characterized by abnormal development of the brain and the bones of the skull. The neural tube is a narrow channel that normally folds and closes between the 3rd and 4th weeks of pregnancy, forming the brain and spinal cord of the embryo. Anencephaly occurs when the 'cephalic' or head end of the neural tube fails to close, causing the absence of a major portion of the brain, skull, and scalp. Infants with this disorder are born without a forebrain (the front part of the brain) and a cerebrum (the thinking and coordinating part of the brain). The remaining brain tissue is often exposed (not covered by bone or skin). Affected babies are usually blind, deaf, unconscious, and unable to feel pain. Almost all babies with anencephaly die before birth, although some may survive a few hours or a few days after birth. Anencephaly is likely caused by an interaction between genetic and environmental factors , many of which remain unknown.

OMIM : 56 Anencephaly is characterized by the absence of cranial vault and brain tissues in the fetus. It is considered an extreme form of neural tube defect (182940) (summary by Singh et al., 2017). (206500)

KEGG : 36 Anencephaly is a congenital absence of a major portion of the brain, skull, and scalp. The primary abnormality is failure of cranial neurulation, the embryologic process that separates the precursors of the forebrain from amniotic fluid. Anencephaly shows a heterogeneous etiology, ranging from environmental to genetic causes. The autosomal recessive inheritance has been reported. Women with elevated levels of plasma homocysteine, low folate, or low vitamin B12 (cobalamin) are at an increased risk of having a child with neural tube defect (NTD). NTDs are the second most common type of birth defects and include anencephaly and open spina bifida [DS:H00262].

UniProtKB/Swiss-Prot : 73 Anencephaly: An extreme form of neural tube defect resulting in the absence of brain tissues, and death in utero or perinatally. Infants are born with intact spinal cords, cerebellums, and brainstems, but lack formation of neural structures above this level. The skull is only partially formed. ANPH inheritance is autosomal recessive.
