Angelman Syndrome 1 AS has been shown in most cases to have a genetic cause. 2  Specifically, it is thought to occur from a problem on a chromosome called 15q11-13 that is passed from a mother to the child. 3  In AS, a part of this chromosome is deleted or not working properly.

Angelman syndrome While Angelman syndrome can be caused by a single mutation in the UBE3A gene, the most common genetic defect leading to Angelman syndrome is an ~4Mb (mega base) maternal deletion in chromosomal region 15q11-13 causing an absence of UBE3A expression in the paternally imprinted brain regions.

A to Z List of Neurological Disorders Issacs' syndrome (also known as neuromyotonia, Isaacs-Mertens syndrome, continuous muscle fiber activity syndrome, and quantal squander syndrome) is a rare neuromuscular disorder caused by hyperexcitability and continuous firing of the peripheral nerve axons that activate muscle fibers.ssacs' syndrome is only one of several neurological conditions that can be caused by potassium channel antibodies. Anticonvulsants, including phenytoin and carbamazepine, usually provide significant relief from the stiffness, muscle spasms, and pain associated with Isaacs' syndrome.

Angelman syndrome Angelman syndrome (/ˈeɪndʒəlmən/ ; abbreviated AS) is a neuro-genetic disorder characterized by severe intellectual and developmental disability, sleep disturbance, seizures, jerky movements (especially hand-flapping), frequent laughter or smiling, and usually a happy demeanor.ngelman syndrome is caused by the loss of the normal maternal contribution to a region of chromosome 15, most commonly by deletion of a segment of that chromosome. Other causes include uniparental disomy, translocation, or single gene mutation in that region.

- What Is Marfan Syndrome? Marfan syndrome is an inherited disorder of the connective tissue, the fibers that provide the framework and support for the body. A patient with Marfan syndrome can't produce fibrillin, a protein that helps to give the connective tissue its strength and elasticity. Marfan syndrome affects connective tissue in the following areas:

HELLP Syndrome and Preeclampsia - Topic Overview HELLP syndrome is a life-threatening liver disorder thought to be a type of severe preeclampsia. It is characterized by H emolysis (destruction of red blood cells), E levated L iver enzymes (which indicate liver damage), and L ow PlateletP count.

- Angelman syndrome is a complex genetic disorder that primarily affects the nervous system. Characteristic features of this condition include delayed development, intellectual disability, severe speech impairment, and problems with movement and balance (ataxia).any of the characteristic features of Angelman syndrome result from the loss of function of a gene called UBE3A. People normally inherit one copy of the UBE3A gene from each parent. Both copies of this gene are turned on (active) in many of the body's tissues.

- HELLP syndrome is a disorder related to preeclampsia and eclampsia (high blood pressure problems of pregnancy). The actual incidence is not known, but it appears to develop in 1 to 2 out of 1,000 pregnancies, and in 10% to 20% of pregnant women with severe preeclampsia or eclampsia.

HELLP SYNDROME HELLP syndrome is a life-threatening pregnancy complication usually considered to be a variant of preeclampsia. Both conditions usually occur during the later stages of pregnancy, or sometimes after childbirth. HELLP syndrome was named by Dr. Louis Weinstein in 1982 after its characteristics: H (hemolysis, which is the breaking down of red blood cells). EL (elevated liver enzymes). LP (low platelet count). HELLP syndrome can be difficult to diagnose, especially when high blood pressure and protein in the urine aren't present.

Angelman syndrome Other characteristics of Angelman syndrome include distinctive facial features, mental retardation, speech problems and hyperactive behaviour. In most cases, the cause is a missing section (deletion) on the mother’s copy of chromosome 15.

Apert syndrome Apert syndrome is a genetic disorder characterized by the premature fusion of certain skull bones (craniosynostosis). This early fusion prevents the skull from growing normally and affects the shape of the head and face. In addition, a varied number of fingers and toes are fused together (syndactyly).

Apert syndrome From Wikipedia, the free encyclopedia. Apert syndrome is a form of acrocephalosyndactyly, a congenital disorder characterized by malformations of the skull, face, hands and feet. It is classified as a branchial arch syndrome, affecting the first branchial (or pharyngeal) arch, the precursor of the maxilla and mandible. Disturbances in the development of the branchial arches in fetal development create lasting and widespread effects.

Angelman Syndrome This phenomenon is called paternal uniparental disomy. Rarely, Angelman syndrome can also be caused by a chromosomal rearrangement called a translocation, or by a mutation or other defect in the region of DNA that controls activation of the UBE3A gene.These genetic changes can abnormally turn off (inactivate) UBE3A or other genes on the maternal copy of chromosome 15.any of the characteristic features of Angelman syndrome result from the loss of function of a gene called UBE3A. People normally inherit one copy of the UBE3A gene from each parent. Both copies of this gene are turned on (active) in many of the body's tissues.

These genetic changes can abnormally turn off (inactivate) UBE3A or other genes on the maternal copy of chromosome 15.n some people who have Angelman syndrome, the loss of a gene called OCA2 is associated with light-colored hair and fair skin. The OCA2 gene is located on the segment of chromosome 15 that is often deleted in people with this disorder.
