Structural organization and expression of the gene for the mouse GM2 activator protein.

Mammalian genome : official journal of the International Mammalian Genome Society

Bertoni C, Appolloni MG, Stirling JL, Li SC, Li YT, Orlacchio A, Beccari T.
PMID: 27518306
Mamm Genome. 1997 Feb;8(2):90-3. doi: 10.1007/s003359900364.

The GM2 activator protein is an essential component for the degradation of GM2 ganglioside by hexosaminidase A in vivo. Mutations in the human gene coding for the GM2 activator protein cause the AB variant of GM2-gangliosidosis, a condition that...

Tongue atrophy and fasciculations in transthyretin familial amyloid neuropathy: An ALS mimicker.

Goyal NA, Mozaffar T.
PMID: 27066555
Neurol Genet. 2015 Jul 30;1(2):e18. doi: 10.1212/NXG.0000000000000018. eCollection 2015 Aug.

OBJECTIVE: Macroglossia is a well-known feature of amyloidosis; however, tongue atrophy and fasciculations are rarely seen and can lead to the misdiagnosis of amyotrophic lateral sclerosis (ALS).METHODS: We identified 2 unrelated patients with atypical features of tongue atrophy and...

Utility of serum lysosomal enzyme assay in the detection of cerebral sphingolipidoses in patients with progressive neurologic dysfunction.

Indian journal of clinical biochemistry : IJCB

Christopher R, Shetty KT.
PMID: 23100874
Indian J Clin Biochem. 1997 Jul;12(2):102-7. doi: 10.1007/BF02873671.

The cerebral sphingolipidoses which form part of a larger group of lysosomal disorders can be detected and conclusively confirmed by the demonstration of the relevent enzyme deficiency in easily available tissue samples like serum. We have assayed acid β-galactosidase,...

Dysarthria and Stutter as Presenting Symptoms of Late-Onset Tay-Sachs Disease in Three Siblings.

Movement disorders clinical practice

Grim KK, Phillips GD, Renner DR.
PMID: 30363497
Mov Disord Clin Pract. 2015 Jun 30;2(3):289-290. doi: 10.1002/mdc3.12194. eCollection 2015 Sep.

Late-onset Tay-Sachs disease (LOTS) is a rare autosomal-recessive genetic disorder caused by insufficient activity of the lysosomal enzyme, beta-hexosaminidase A, resulting in intracellular accumulation of gangliosides in the central nervous system. Clinical manifestations can include unsteadiness in gait, muscle...

Urine proteomics analysis of patients with neuronal ceroid lipofuscinoses.

iScience

Iwan K, Clayton R, Mills P, Csanyi B, Gissen P, Mole SE, Palmer DN, Mills K, Heywood WE.
PMID: 33532713
iScience. 2020 Dec 31;24(2):102020. doi: 10.1016/j.isci.2020.102020. eCollection 2021 Feb 19.

The neuronal ceroid lipofuscinoses (NCL) are a group of 13 rare neurodegenerative disorders characterized by accumulation of cellular storage bodies. There are few therapeutic options, and existing tests do not monitor disease progression and treatment response. However, urine biomarkers...

BACKGROUND AND AIM: Jacob sheep are a rare ancient breed of sheep believed to have originated from the Mediterranean area but which are now kept throughout the world. These sheep have recently attracted medical interest due to the observation...

Late-Onset Tay-Sachs Disease in an Irish Family.

Movement disorders clinical practice

Lefter S, O' Mahony O, Sweeney B, Ryan AM.
PMID: 33426165
Mov Disord Clin Pract. 2020 Oct 28;8(1):106-110. doi: 10.1002/mdc3.13096. eCollection 2021 Jan.

BACKGROUND: Late-onset Tay-Sachs disease (LOTS) is an autosomal-recessive lysosomal storage disease caused by deficient β-hexosaminidase A activity. LOTS is rare in the Ashkenazi Jews, but even rarer in the non-Jewish population.CASES: We report an Irish family expanding the LOTS...

Neural Regen Res. 2022 Jan;17(1):122-129. doi: 10.4103/1673-5374.314310.

Tay-Sachs disease and Sandhoff disease are severe hereditary neurodegenerative disorders caused by a deficiency of β-hexosaminidase A (HexA) enzyme, which results in the accumulation of GM2 gangliosides in the nervous system cells. In this work, we analyzed the efficacy...
