Presentation
The lysosomal enzyme deficiencies known to produce certain forms of spinocerebellar degeneration were not present in Friedreich's disease or the Charlevoix-Saguenay syndrome. [ncbi.nlm.nih.gov]
This is the first Korean case of adult Sanhoff disease presented as a motor neuron disease phenotype. Key words: Sandhoff disease, Motor neuron disease, GM2 gangliosidosis [e-acn.org]

Limb Weakness
At her first clinical examination, when she was 20 years old, she presented ataxia in her trunk and limbs, muscle atrophy, and limb weakness. [nature.com]
Workup
Additionally, the biochemical workup for TSD could be completed with MUGS testing without collecting a new specimen. [mayomedicallaboratories.com]
Workup and physical examination Both homozygotes and heterozygotes have a reduced concentration of sphingomyelin in their RBCs. Affected individuals have deficient Hex A activity and normal levels of the Hex B isozyme. [emedicine.medscape.com]

Furthermore, we will examine the effect of the treatment on the levels of GM2-ganglioside in the white blood cells. [clinicaltrials.gov]
Prognosis
Prognosis In general terms, the earlier the presentation, the worse the prognosis. The prognosis for all forms of beta Hex deficiency is poor, with most sufferers dying in childhood. [patient.info]
(Outcomes/Resolutions) Sandhoff Disease is associated with a poor prognosis. [dovemed.com]
Treatment and prognosis Therapy primarily centers on hematopoietic stem cell transplantation which can delay disease progression 11. Prognosis depends to a large degree on the age at which a diagnosis is made. [radiopaedia.org]

Etiology
(Etiology) Sandhoff Disease is caused by the deficiency of 2 enzymes, which include: β-hexosaminidase A and β-hexosaminidase B The deficiency of these enzymes is due to an abnormal (mutated) gene called HEXB. [dovemed.com]
Epidemiology
Epidemiology [ 2 ] This is a rare group of disorders affecting approximately 3.22 per million non-Jewish newborns (compared with 1 in a million Jewish newborns - a distinction with TSD where there is an increased prevalence in the Ashkenazi Jewish community [patient.info]

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test Tay-Sachs and Sandhoff diseases are lysosomal storage disorders, also referred to as GM2 gangliosidoses, caused by deficiencies [mayomedicallaboratories.com]
The adult form of the disease, however, is sometimes milder, and may only lead to muscle weakness that impairs walking or the ability to get out of bed. [ 17 ] Pathophysiology Sandhoff disease has an autosomal recessive pattern of inheritance. [dictionnaire.sensagent.leparisien.fr]
