Alpers Disease - NORD (National Organization for Rare

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.

Projevuje se především glomerulárním postižením (glomerulonefritida s hematurií, a posléze proteinurií, progredující do stadia chronického selhání ledvin. Alportův syndrom je vzácné geneticky podmíněné vrozené onemocnění, které se týká zejména postižení ledvin a smyslových orgánů. Nemoc se vyskytuje jen asi u 1 z 50,000 narozených dětí.

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
