Alpers disease is a progressive neurologic disorder that begins during childhood and is complicated in many instances by serious liver disease. Symptoms include increased muscle tone with exaggerated reflexes (spasticity), seizures, and loss of cognitive ability (dementia) Alportův syndrom a historie. Alportův syndrom je pojmenován podle britského lékaře A. Cecila Alporta, který v roce 1927 popsal tři generace rodiny s kombinací progresivní dědičné nefritidy a hluchoty. Dr. Alport také zjistil, že krev v moči (hematurie) je nejčastějším příznakem, a že muži byli postiženi závažněji.

Alpers' disease is a progressive, neurodevelopmental, mitochondrial DNA depletion syndrome characterized by three co-occurring clinical symptoms: psychomotor regression (dementia); seizures; and liver disease. It is an autosomal recessive disease caused by mutation in the gene for the mitochondrial DNA polymerase POLG
Alpers-Huttenlocher syndrome is one of the most severe of a group of conditions called the POLG -related disorders. The conditions in this group feature a range of similar signs and symptoms involving muscle-, nerve-, and brain-related functions. Alpers-Huttenlocher syndrome typically becomes apparent in children between ages 2 and 4 Mitochondrial DNA depletion syndrome (MDS or MDDS) is any of a group of autosomal recessive disorders that cause a significant drop in mitochondrial DNA in affected tissues. Symptoms can be any combination of myopathic, hepatopathic, or encephalomyopathic. These syndromes affect tissue in the muscle, liver, or both the muscle and brain, respectively 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

Alpers-Huttenlocher syndrome (AHS) is a rare autosomal recessive disorder that is characterized by seizures, liver dysfunction, and progressive developmental regression that leads to early death. Children appear healthy at birth and usually develop normally until the onset of their illness. The average onset of disease is between 2 - 4 years.
Alpers disease usually begins in early childhood, predominantly affects the cerebral gray matter, and is characterized by progressive dementia and/or regression (loss of milestones), growth retardation, audiovisual impairment (blindness is possible), intractable seizures, myoclonus, ataxia, spasticity, areflexia, nystagmus, hypotonia, partial paralysis, dysphagia, and often liver damage Alpers' Syndrome is an inherited mitochondrial disease that generally effects younger children with symptoms usually visible before the age of five. Without treatments to slow the disease's progression, the affected children do not normally live long after their symptoms appear. While both parents may not have the disease, they may carry.

Although Alpers-Huttenlocher syndrome has a restricted neuro-hepatic presentation, mutations in this same gene can result in a broad range of clinical presentations that involve not only the brain and liver, but the rest of the central and peripheral nervous system as well as the cardiac, endocrine, and reproductive systems Alpers syndrome is a heterogeneous syndrome that should be considered in patients with early-onset progressive cortical encephalopathy regardless of liver involvement.

Alpers Syndrome, also known as Alpers-Huttenlocher Syndrome, is an inherited genetic illness that affects the production of energy on a cellular level. Alpers is one of many mitochondrial illnesses and can be diagnosed with a DNA test of the POLG1 gene
This is a next generation sequencing (NGS) test appropriate for individuals with clinical signs and symptoms, suspicion of, or family history of Alpers-Huttenlocher Syndrome. Sequence variants and/or copy number variants (deletions/duplications) within the POLG gene will be detected with >99% sensitivity Described are six patients with Alpers syndrome from four unrelated families. Affected individuals harbored the following combinations of POLG mutations: 1) A467T/W1020X, 2) W748S-E1143G/G848S, 3) A467T/A467T, and 4) A467T/G848S. Homozygosity for the A467T allele in one patient was associated with a later age at onset. Mitochondrial respiratory chain studies in skeletal muscle were normal in. A rare genetic syndrome with an autosomal recessive pattern of inheritance. It is caused by a mutation in the gene for the mitochondrial DNA polymerase POLG. Clinical signs are usually not present at birth but develop within the first two years of life and include hypoglycemia from underlying liver dysfunction, failure to thrive, spasticity, myoclonus and seizures. The clinical course follows. Alpers' syndrome is a mitochondrial disease that is part of a larger group of conditions collectively known as mitochondrial DNA depletion disorders. It is most often caused by mistakes in the DNA of a gene called POLG (pronounced pawl-gee) and is part of a spectrum of POLG-related diseases. There are a number of other, extremely rare.
